某车型上推力杆结构改进

A Model On Thrust Bar Structure Improvement

重型汽车上推力杆在使用过程中杆头发生断裂失效比例较大,经过对售后件分析及安装位置分析建立受力分析模型,进行有限元计算,并根据有限元分析结果进行优化设计。针对优化后推力杆经行拉伸、扭摆、偏转等疲劳试验,及装车路试表明优化后推力杆可满足该车型的使用强度。

Heavy-duty truck thrust bar rod head a higher percentage of fracture failure occurs in the process of using, after analyzing the after-sales parts and the installation location analysis force analysis model is established, finite element calculation, according to the result of finite element analysis and optimization design. According to the optimized thrust rod by the line drawing, twist, deflection, such as fatigue test, and the loading road tests show that the optimized thrust rod can meet the intensity of use of the model.
