1/4차량의 가상노면형상의 재구성

For the evaluation of ride quality and durability analysis of vehicle components by computer simulation, it is indispensable to consider nonlinear characteristics of tire and road. Most linear tire models are restrictive to represent this effect in the simulation. This paper proposes how to regenerate the road profile which preserves the measured wheel accelerations at the wheel center with linear tire model. The new road profile compensates for the difference of wheel acceleration between experiment and simulation using the frequency response function. The validity of the method was verified by appling to a 1/4 car model.
