摘　　要：转向力是汽车操纵稳定性中一项重要的评价指标,其力矩波动直接影响驾驶感觉。文章对汽车转向轴的布置与力矩波动的关系进行了分析,并针对某车型转向系统的十字轴万向节结构进行优化设计。优化结果在matlab软件里仿真,得到较好的结果,波动力矩在允许的范围内。并得出最佳的中间轴相位角及轴系布置方案,对转向系统的优化设计有一定的参考价值,可作为实际车型开发中传动优化设计的技术依据。Steering force is a very important evaluation index in vehicle controll stability;the torque fluctuation directly affects driving feeling.The relationship between the steering shaft arrangement and torque fluctuations is analyzed,and optimization design of cross axis universal structure in a car steering system is conducted.The optimization results are simulated in Matlab software and better results are achieved.The fluctuation torque is in permitted range.The best countershaft phase angle and shafting arrangement solution is gained.It provides reference for optimization design of steering system;and it can be used as technical basis of transmission optimization design in developing automobiles.
