In the vehicle durability analysis, it is necessary to predict the load in the bushings using an accurate model. Upon the request from Chrysler Canada Inc., a new bushing model, called the Advanced Bushing Model (ABM), is proposed and discussed. The ABM contains five modules dealing with the nonlinearity, asymmetry, and hysteresis presented in common bushings. Both stiffness and damping modules are nonlinear, and the hysteresis module is represented by the Bouc-Wen hysteretic model. A mass module is also introduced for inertia consideration. To accommodate the frequency dependency of the hydro-mounts, a transfer function module is deployed. The ABM is parameterized using MATLAB in the time domain, and the fitted result is available for other software. The fitness events demonstrate that the ABM is ideal for modeling rubber bushing, acceptable for hydro-mount, and promising for damage reproduction. More fitting events are necessary to gain user experience and improvement of the ABM.
