汽车多轴转向摇臂机构的优化设计

Modeling and Optimiaation of Steering Rods of Multiaxile Steering Automobiles

多轴转向汽车的杆系合理匹配是十分重要的，不仅同一轴两车轮转角之间应互相匹配，而且不同的转向轴同侧车轮之间的转角也应很好的匹配。这一点是多轴转向汽车与单轴转向汽车的根本区别。本文以双桥转向汽车为例，分析了多轴转向汽车数学模型的建立方法，并对两转向轴之间的摇臂机构进行了运动分析，在此基础上进行了优化设计，仿真结果验证了该方法的正确性。

Steering rods′ optimiaztion of multiaxile steering automobiles is very important It relates to not only the optimization of steering rods of two wheels between left and right of together axle,but also the optimization of steering rods between multi steering axles This paper holds a new modeling and optimization method of kinematics and dynamics of steering rods of multiaxile steering automobiles Again, the paper uses a two axles steering automobile as an example for analyzing and verifying the method, and ges the optimization result of rods
