E-Silence: reducing e-powertrain NVH behavior without deteriorating performance or increasing cost

The E-Silence R&D project is developing optimization methodologies and solutions to tackle NVH issues, starting at the early design phase and going up to the prototype phase. Our optimization algorithms are able to test several thousands of motor topologies in a short period, ensuring a noise minimization which is robust regarding manufacturing tolerances.

We have already used these methods on several industrial applications: noise reduction is more than 10 dB, without any deterioration of the other global machine performances (torque, efficiency, etc), and without increasing mass and cost.

We also optimize stator potting material in order to reduce noise by 10 to 20 dB.

VibraTec is proud to coordinate the project with its partners Altair, Moving Magnet Technologies and research laboratories FEMTO-ST and L2EP.

VibraTec will present the E-Silence project at the CARA cluster’s online Automotive Techdays on June 1st: feel free to stop by our booth to talk with us about the project !

This project was partially financed by the European Union through the ERDF.

Indirect rail acoustic roughness measurements using an onboard system

Indirect rail roughness measurement makes it possible to estimate the acoustic quality of a railway infrastructure without space or time constraints. Several indirect measurement systems for rail acoustic roughness exist, based on different vibro-acoustic sensors. However, these systems present a number of limitations that VibraTec has overcome with its unique hybrid numerical/experimental approach.

Numerical simulations serve to select the best set of sensors (type, number and position), making it possible to overcome any potential frequency limitations. Numerical simulation also takes the influence of track dynamics into account. Experimental calibration completes the roughness measurement methodology.

This work was developed in the framework of the French project MEEQUAI (on-board MEasurement of railway Infrastructure Acoustic QUality). The project involved a partnership with the Joint Research Unit in Environmental Acoustics at the Université Gustave Eiffel (UMRAE) and the French national railway company SNCF.

Listen to Anna-Rita TUFANO’s presentation at the e-Forum Acusticum in December 2020.

VibraTec proud to organize 1st LIVE-I public event in 2021

The LIVE-I project, short for Lightening and Innovating transmission for improving Vehicle Environmental Impacts, seeks to achieve breakthrough technological progress in the design of lightweight gear transmissions and to build an innovative training network. The consortium, coordinated by the Ecole Centrale de Lyon (France), is composed of 6 universities and 6 industrial partners, and includes institutions from European and non-European countries to build a strong and fruitful joint experience in cooperation and research.

The 1st event this year is a day dedicated to “Noise Vibration Harshness of gear transmissions”, organized by @VTC on January 25th. This training day, open to the public, offers the opportunity to better understand the physics that control noise and vibration of gears. Christian CLERC, Alexandre CARBONELLI, Jessica NEUFOND, Jean-Baptiste DUPONT, and Joël PERRET-LIAUDET (ECL) will share the floor throughout the day.

After a reminder of the theory and mechanisms that cause vibrations and sound radiation (from the contact forces between the teeth to the dynamic response of the casing), modeling tools and their use to solve industrial cases will be presented. Finally, recent developments on the simulation of complex gears and on the coupling with electric machines will be presented.

Knowledge of these phenomena is gaining importance with the development of hybrid and electric motor vehicles, but is also pertinent in other areas of industry.

Participants from both academia and industry are welcome. Maximum number is 50. Participation is free of charge: registration is mandatory before January 20th, 2021.

VibraTec – designing pragmatic, innovative solutions

The ICTUS project (Instrumented engine Cradle for the TUrboprop demonstrator ground teSt) consisted in the design, manufacturing and qualification of the Tech-TP aircraft engine cradle. The project had four major objectives:

  • Design for flight and manufacture of the cradle supporting the engine and nacelle,
  • Provide a dedicated cradle instrumentation to manage loads, temperature and vibration,
  • Address the engine air flow environment,
  • Measure operational static & dynamic engine loads.

The ICTUS program has strongly contributed to the delivery of the first key demonstrator in Cleansky2 with the manufacturing of the cradle. The proposed instrumentation combined to the development of advanced test methods offers a major breakthrough to improve the exploitation of static engine test beds. It opens new ways to predict the engine interface within its aircraft environment for both engine and aircraft manufacturers.

E-powertrain design to reach performance and NVH targets

Often, the first E-powertrain prototype does not correspond to NVH specifications. At this stage, there is little time for re-design, and only slight modifications are possible to address NVH requirements without performance loss.

VibraTec has developed a multiphysics optimization algorithm that takes client targets and constraints into account. The algorithm optimizes several parameters, virtually guaranteeing that NVH specifications will be respected.

With a unique combination of gear and electric motor optimization,  VibraTec’s algorithm reduces acoustic power levels at critical operating points by at least 5 dB, and up to 20 dB in certain cases. NVH specifications are fulfilled, performance and manufacturing processes are maintained and no acoustic treatment is required.

Bearing and gear fault detection using Machine Learning

Maintenance services are beginning to use conditioned-based maintenance with vibration sensors. New methods in signal post-processing are being coupled with Machine Learning (ML) algorithms.

The method proposed by VibraTec is to add a qualitative analysis in case of fault detection (bearing or gear faults, etc.)

This new step helps maintenance services to focus more efficiently on the faulty part of the system, inducing more rapid repair. This involves less downtime, leading to significant gains in productivity.

This research work was developed for maintenance services, in order to increase the efficiency, maintenance scheduling, and organization.

The work, focusing on the railway sector, was developed in the scope of the Run2Rail project (Shift2Rail). However, it can be applied to any industrial sector (aeronautics, automotive, etc.).

VIBRATEC is now proposing a maintenance aid service for railway networks

VIBRATEC has been involved in track and rolling stock dynamic behavior analysis for over 30 years, using both measurement techniques in operation and interaction models between rail and rolling stock.

Using its expertise, VIBRATEC is now proposing a maintenance aid service. This service is based on two approach, experimental and numerical:

  • a smart autonomous monitoring system to detect rail defects (squat, corrugation, squealing,…),
  • a digital (virtual) approach to evaluate the remaining life of your rolling stock and rail.

Data are not only used for condition monitoring but also to prompt maintenance operations.  VIBRATEC’s asset management aims to shift from a reactive maintenance mode to a proactive one; to ensure the durability of your asset and to optimize the exploitation to extend the service life of the rail and the rolling stock.

CM 2018 in Delft, Netherlands: Rail joint dynamic forces computations, including rail plasticity

Vibratec will present a publication which is divided in two subjects:

  • Benchmark of 3D FE model compared to simplified model, to compute wheel-rail contact forces at rail joints: the objective is to validate the simplified approach in order to perform fast parametric variations
  • Computations of contact force including rail plasticity using 3D FEM: the objective is to assess the influence of plasticity on the contact force amplitude.

The subject started with SNCF, for which 3D FE models were developed to compute dynamic force for fatigue assessment.

VIBRATEC then decided to enhance the model by including rail plasticity (Chaboche model) and compared it to other numerical model, in collaboration with IFSTTAR, who developed the VOCO software which is used for parametric variations

VibraTec – tackling railway measurement & simulation issues for more than 30 years !

VibraTec has been working in the railway field for more than 30 years and has capabilities in measurements and simulations. Two issues are growing inside the scientific community in the railway fields: maintenance with cost reduction at stake, and the environmental impact due to increasing demand in urban areas.

VibraTec is taking part in the state-of-the-art advance in these two subjects, and will present 3 papers at the upcoming ICRT Conference in ChengDu, China.

The first paper is related to maintenance. In a study performed for the SNCF (French national railway institution), a comprehensive finite element model has been set up to compute the time domain contact force due to a rail joint. Predicting the contact force will help to control the stress in the track and hence help to reduce maintenance. Both the difficulties encountered and the final results will be presented.

The two other papers are dedicated to ground-borne noise and vibration issues. First, a benchmark of soil-building numerical models has been performed with the CSTB (French national building institute of research) to compare and highlight the differences between a 2.5D FEM-BEM approach and a 3D FEM approach. Several application cases are developed to present the pros and cons of each model.

Secondly, VibraTec and Acouphen are presenting their practical methodology to characterize soil by measurements. Measurement quality is evaluated on-site by a step-by-step process. The excitation must be chosen according to preliminary results and adapted if necessary.

If you want to know more, join us in ChengDu from the 10th to 12th of July !

Dynamic response: a pertinent indication of structural mechanical reliability

Christian Clerc, VibraTec’s Scientific Director, will participate in a roundtable regarding “The importance of infrastructures: resilient, dynamic urban ecosystems serving connected mobility” during the « Revue annuelle des nouveaux usages consacrée à la mobilité » organized by the ANRT (National Association for Research & Technology) on June 15th in Bezos (Paris), France.

Anticipating failures, preventing passenger discomfort and noise pollution, optimizing maintenance at reduced cost are essential elements of railway infrastructure management.

  • Goal: take advantage of new IT and communication technologies to capitalize on 30 years of experience in acoustics and dynamics in the transportation field.
  • Digital technology contribution: vibratory and acoustic signatures provide information regarding the condition of both rolling stock and track and can therefore be analyzed to monitor wear and prevent failure. What used to require costly and fastidious measurement campaigns can now be integrated in an autonomous connected object thanks to new technology: MEMS captors, integrated processors & wireless communication.
  • Application: in the transportation field, on-board objects can be compact and intelligent, capable of measuring, analyzing and communicating in real-time the mechanical evolution of the structure or system to which they are applied. They will function on recovered vibration energy.
  • The railway application addressed by the MaViCo project aims to identify, localize and monitor various defects. The final product will serve to optimize mid-term maintenance (slow wear) as well as to prevent breakdowns (broken track, leaves/deposits on the track) and to avoid noise pollution (from screeching for instance).

VibraTec Asia Pacific to be part of Rail Solutions Asia 2017

VibraTec Asia Pacific Project & Business Manager Ravindran KALIDAS will be presenting a paper addressing “Robustness and Reliability of Railway Equipment” at the Rail Solutions Asia Event in Kuala Lumpur on May 25th.

Railway equipment – both rolling stock & infrastructures – is subjected to high mechanical stress that must be integrated from the design stage. Standards have been established, but do not always guarantee reliability. This paper details the in-house methodologies (using calculation and testing) that provide more relevant input data for conception and use; realistic loads for models, realistic conditions for experimental validation, implementation of a loading database, feedback on the use of different materials and material residual life duration study results.

COnnected MAintenance using VIbration measurements

MaViCO aims to develop a new generation of conditioned maintenance tool for the railway industry, using an energy-autonomous defect detector based on vibration analysis that will be capable of acquiring, processing and transmitting data in view of facilitating conditioned / predictive rail / rolling stock maintenance.

Mounted on the track, it will detect wear in specific sensitive zones of the infrastructure (switch and crossing area or transition area) and/or detect rolling stock defects (influence of the rolling stock). Mounted on the rolling stock, it will detect track wear defaults (corrugation, defective rail joints, squats, etc). 

This collaborative project, co-financed by the ADEME (French Environment & Energy Management Agency) and implicating the VapéRail and Kéolis companies as well as the LaMCoS (INSA Lyon) lab, started at the beginning of this year: the technical scope is currently being tuned to meet customer expectations.

Technicians - we are recruiting !
If you are a noise &/or vibration specialist, this could be the perfect occasion to enrich your experience: our group, well-known for its expertise in acoustics and structural dynamics, works on very diversified projects.
