In addition to the health risks, vibrations can also affect MWC lifetime and function. At a given set of excitation frequencies (i.e., MWC eigenfrequencies), interactions between the inertial and elastic properties of the structure materials cause a resonance phenomenon [11]. In the long term, the repetition of the local deformations induced by the resonance phenomenon can cause cracks, loose screws, bolts, mechanical fatigue, or even failure of the MWC [12].
To protect the user and preserve the MWC lifetime, a dynamic model of the MWC needs to be used. As the characteristics of the WBV reaching the MWC user depends on both the user (e.g., their morphology, posture, and muscular activation) and the MWC dynamical behaviour [13,14], modifying an MWC setting/parameter rarely shows systematic effects on WBV exposure. To address this issue, one solution is to develop a dynamic model of the MWC/user dyad exposed to vibration. Until now, only a few authors have tried to model the vibration transmissibility during MWC propulsion [13,15,16,17]. Except for Mastuoka et al. [13,17], most studies have focused on a mechanical model of the seated able-bodied human [6], neglecting the MWC. The model proposed by Mastuoka et al. [13,17] considers the MWC as a single rigid body, preventing a parametric study of the MWC settings. By using a parametric model of the MWC, it is possible to account for the individual vibration response of each MWC/user dyad.
