    COnnected MAintenance using VIbration measurements
Ground-borne noise / vibration

VibraTec is able to call on a large database of actual results, established from over 30 years of measurements on rolling stock and lines. This extensive database allows Vibratec to use real data for most scenarios and therefore bring a realistic approach to the design process. VibraTec is able to develop technical specifications for project equipment and infrastructures to enable the project to achieve the objectives of lifetime, acoustic and vibratory comfort and environmental impact. VibraTec’s experts understand the constraints of rolling stock and the dynamic interaction on bogie or body onboard equipment. With extensive experience of infrastructures and different track components, Vibratec are able to establish representative computational models for elements such as ground vibration, noise pollution, lifetime and durability etc. Application case: 3rd rail current collection shoe

VibraTec has developed a calculation method to optimize design depending on the loads present in operation. VibraTec is able to design mechanical components according to existing standards (NF EN 61 373, NF EN 12 663, etc.). Where the standards do not provide sufficient guidance to obtain a robust design, Vibratec has developed an equivalent damage approach. VibraTec has extensive experience in writing technical specifications for equipment manufacturers and test laboratories. VibraTec is able to provide complete monitoring laboratory tests which include all necessary instrumentation.
