Design and optimization of the front suspension system for a four-wheel-drive BAJA racing cars
摘要
Abstract
The optimal design and analysis of the front suspension system for a 4WD BAJA racing car were conducted.Based on the experience from previous races,a dynamic model of the front suspension system was established using ADAMS/Car.Simulation and optimization were then conducted on key alignment parameters,including toe angle,kingpin inclination angle,kingpin caster angle,and wheel camber angle.The results showed that after optimization:the variation range of the toe angle was significantly narrowed to-1°～1°;the kingpin inclination angle was adjusted to 9.75°～11.40°;the kingpin caster angle was controlled within 1.94°～2.80°;the wheel camber angle ranges from-0.7°～1.0°.This optimization effectively enhances the suspension handling stability and steering precision,providing a theoretical reference for the design of four-wheel-drive Baja racing suspension.关键词
