基于小型赛车的悬架第三弹簧装置的设计

Design of Third Spring Device of Suspension Based on Kart

为解决横向稳定杆不能提供抗俯仰的问题,提高赛车性能以及操作稳定性,设计一套第三弹簧装置。结合轮胎数据与整车参数设计确定悬架硬点,通过Adams对该悬架进行仿真分析验证,结合实车试验,结果表明第三弹簧装置能有效抑制赛车在制动时的点头行为。

In order to solve the problem that the stabilizer bar cannot provide anti-pitching and improve the performance of the car and the stability of operation,a third spring device is designed.Combining tire data and vehicle parameter design to determine the hard points of the suspension,simulation analysis and verification of the suspension through Adams,combined with the actual vehicle test,the results show that the third spring device can effectively restrain the nodding behavior of the car when braking.
