| 摘 要： | 利用动力学分析软件ADAMS,从汽车转向运动学出发,分析了SGA3550型自卸式汽车全液压转向机构的设计。首先以汽车转向时实际转角与理论转角误差最小为优化目标,以转向梯形底角和梯形臂长为设计变量,对转向梯形机构进行了优化设计。其次,说明了全液压转向机构中转向动力油缸的设计计算过程。最后,通过仿真分析,比较了不同数量液压油缸设计方案对转向性能的影响。

| Abstract: | ADAMS software is used to finish a design on hydraulic steering mechanism of SGA3550 truck based on steering kinematics.Firstly,the optimization design of steering mechanism is done,and design variables are the bottom angle of steering trapezoid and the length of trapezoid arm,and objective function is minimum error between theoretical steering angle and practical steering angle.Secondly,the design method of hydraulic cylinder is introduced.Lastly,the performance on steering mechanics of different number of hydraulic cylinder is compared by the simulation analysis. |
