Open publisher page 1 citations

Abstract

When vehicle driving on turning, its easy to rollover because of high speed and large steering angle. Aim at Sports Utility Vehicle, a rollover dynamic model of three degree of freedom is established and used to simulation test of typical cornering. The relation of steering wheel, steering wheel rotation speed and suspension stiffness to vehicle rollover characteristics was analyzed by Fishhook simulation test. Then, the sensitivity analysis was carried out to confirm the biggest factor influencde vehicle rollover.
