汽车双横臂扭杆弹簧独立悬架设计

The design of double wishbone torsion bar spring independent suspension for car

文章主要研究某轻型载货汽车前独立悬架的设计计算方法以及独立悬架的设计试验验证,首先对双横臂式独立悬架进行受力分析、运动轨迹计算,然后对悬架进行设计计算如扭杆弹簧的设计、前悬架的刚度、偏频计算、稳定杆的设计、侧倾刚度计算、减震器的设计,最后通过试验验证悬架的偏频、平顺性。

This paper is mainly to analysis a light truck’s computing method of the front independent suspension design and testing of design experiment. Firstly, it goes with the stress analysis and the trajectory calculation of the double wishbone independent suspension, and then continues with the suspension design calculation such as the design of torsion bar spring , front suspension’s stiffness, offset frequency calculation, stabilizer bar’s design, roll stiffness calculation, shock absorber’s design, and finally the suspension offset frequency and riding comfort can be verified through the test.
