The Effects of Flexible Modeling of the Typical Component of Double Wishbone Independent Suspension on Vehicles Transient Response
In this paper, in order to study the effects of flexible modeling of the typical component (lower control arm) of the double wishbone independent suspension on vehicles transient response characteristics, a flexible model of lower control arm is established by using the finite element modeling software MSC/PATRAN and the finite element analyzing software MSC/NASTRAN firstly, and then the vehicles multi-rigid-body dynamic model and the vehicles rigid-flexible coupling multi-body model are established in the CAR module of the mechanical system simulation and analysis software MSC/ADAMS. Finally virtual tests under the steering wheel step steer angle input are carried out. Vehicles yaw angle velocity is used to characterize the vehicles transient response. Experimental results indicate that compares with the multi-rigid-body dynamic model, the peak value of the yaw angle velocity of rigid-flexible coupling multi-body model is small, the response is slow and the steady state value of yaw angle velocity of two models become close to each other with the increase of vehicle velocity. This paper also provides a feasible approach to study the effects of flexible modeling of other suspension components on vehicles transient response and a more precise research on the suspensions performance.
