Étude du comportement vibratoire du système main-bras en cyclisme

Abstract : Vibrations transmitted to hand-arm system can have fatal consequences for the health of individuals, that is why the vibration exposure is framed in the workplace to limit the occurrence of musculoskeletal disorders among employees. Many numerical models of hand-arm system are proposed in the literature, these are mainly access to the use of vibrating hand tool. The first part of the study concerns the creation of two numerical models of hand-arm system, in order to simulate the transmission of vibrations throughout the hand-arm system. The first model is composed of elements mass-spring-damper, and the second element of the beam type. The first model is composed of elements mass-spring-damper, and the second of beam type element. The second part of the study is experimental, and concerns the transmission of vibration in the hand-arm system in cycling, because the professionals who accumulate training hours can be highly stressed, especially when passing over paved roads. Test to study the transmissibility has been made, and the calculation of the maximum daily exposure of the directive 2002/44/EC using the standard ISO 5349. This led to propose a new weighting curve of the standard, taking into account the structure of the bicycle.
