摘要
针对该赛车参赛过程中出现的转向回正力过大、过度转向趋势以及抗制动点头造成球铰间隙过大等问题,首先采用"二次瞬轴法"设计多连杆悬架虚拟主销,应用多体动力学仿真软件ADAMS/Car模块建立前悬架与转向系统虚拟样机;在此基础上对主销后倾角、车轮外倾角、前束角及抗制动纵倾性四个参数仿真并应用ADAMS/Insight模块进行多目标优化设计;优化后的多连杆悬架主销参数能够提供适当的回正力矩,外倾角与前束角共同作用能使得赛车具有轻微的不足转向趋势,提高了赛车的操纵稳定性,同时赛车抗制动点头现象也得到明显改善,为在大学生方程式赛车中的多连杆悬架设计和优化提供了参考。
Aiming at the the shortage of the car in the course of the competition turned back positive force is too large,oversteer tendency and anti brake nod caused by spherical hinge gap is too large,this paper through the "two instantaneous axis method" to design the kingpin axis of the multi link suspension and use the multibody dynamics simulation software ADAMS/Car to build the front suspension and steering system virtual prototype;Besides,the four parameters of the caster angle,the camber angle,toe angle and the anti-braking deflection are simulated and the multi-objective optimization design of the ADAMS/Insight module is carried out;After optimization,the parameters of multi link suspension can provide the proper steering retumability,the combined effect of camber angle and toe angle can cause the car to have the tendency of understeer and improves the handling stability of the vehicle and the anti- braking nod also gets obvious improvement.Finally,it provides a reference for the multi link suspension design and optimization in formula society of automotive engineers racing car(SAE).
