| 摘 要： | 针对某车型扭杆式双横臂独立悬架前轮距加宽的要求,提出了改型设计的几种方案,并根据轮距和定位参数随轮跳变化的曲线趋势确定了最优方案.建立了扭杆式双横臂独立悬架虚拟样机模型,通过对比静态平衡位置时定位参数的理论值与仿真值,验证了模型的准确性.通过分析5种运动特性曲线变化趋势可知,前束角变化最为灵敏,从而可确定上下摆臂各加长40mm、转向器长度不变、转向拉杆每侧加长40mm的方案为最优.

| Abstract: | To satisfy the requirement of widening the front tread of torsion bar spring double-wishbone independent suspension of a vehicle model, several remodeling designs are proposed, and the best design is defined based on curve trend of tread and positional parameters with variation of wheel jump. A virtual prototype model of the torsion bar spring double-wishbone independent suspension is set up. By comparing the theoretical values and simulation values of the positional parameters at static equilibrium, the mo... |
