双桥系统的推力杆平衡及弹性支撑的分析

The Auto Double Bridge Thrust Bar Balance and Analysis of the Elastic Support

首先介绍了重型汽车平衡悬架用推力杆的工作原理,建立了重型汽车平衡悬架用推力杆的简单受力模型。当中桥车轮受到冲击载荷跳起时,计算中桥和后桥上推力杆的轴向力并校核推力杆的强度。当只有后桥右车轮抬起时,计算后桥上推力杆的扭矩应力并校核其强度。然后,分别建立推力杆总成、壳体、连接杆和小轴的CATIA模型。接着,在以上分析计算结果的基础上,分别对它们进行ANSYS分析。

The thrust bar＇ s working principle was briefly introduced first, which was used for heavy-duty vehicle equalizing suspension. The simple mechanical analysis model of thrust bar for heavy-duty vehicle equalizing suspension was established. When the medium bridge jumping up by the impacted load, the thrust bar＇ s axial thrust force was calculated and the strength of thrust rod checked, located in the medium bridge and rear axle. When the right rear wheel was raised only, the thrust bar＇ s torsional stress was calculated and the strength of thrust rod checked, located in the rear axle. Then the thrust bar assembly＇ s model, connecting link＇ s model and small shaft＇ s model by CATIA were established separately. And then, they were analyzed using ANSYS finite element analysis one by one based on the result of calculation and analysis above.
