摘要
通过几何法为大学生方程式赛车设计了前、后悬架的导向机构,并提出了通过弹簧长度与车轮跳动量之间的关系曲线来确定悬架传动比的方法;利用Adams/Car软件建立了整车多体动力学模型并进行了操纵稳定性虚拟仿真试验。仿真结果表明所设计的前、后悬架在保证传动比恒定的同时可以使赛车具有良好的不足转向特性和转向回正性能。
Guiding mechanism of FSAE front and rear suspension is implemented by geometric method and a method for determining the suspension motion ratio from spring length-wheel travel curve is proposed. With the help of Adams/ Car, multi-body dynamic model of the whole car is established and virtual simulation of handling stability is conducted. The results show that the suspension designed can make the car has good under-steer characteristic and steering return-to-center performance with constant motion ratio.
