Study on Influence Analysis of Vehicle Steering Gains Based on ADAMS/Car of Suspension Torsion Bar and Anti-Roll Bar

Abstract:

In order to study the effect of stiffness of the suspension and anti-roll bar on the vehicle handling performance, and provide reference for suspension design and adjustment afterwards, two virtual prototypes and their variants without anti-roll bar and front suspension assembly anti-roll bar, were structured in ADAMS/Car. Through simulation test with input of steering wheel angle step, the curves of effect of angle stiffness of front suspension torsion bar and anti-roll bar on vehicle steering gain were obtained. On two models, steering gains respectively produced about 20% and 1% decline of the range of experience while the angle stiffness of torsion bar increased from 0.5 to 2.0 times of the base stiffness; steering gain respectively produced about 10% increase or 1% decline of the range of experience while the angle stiffness of anti-roll bar decreased from the base angle stiffness to 0 or increased to 2.0 times of the base stiffness.
