| 摘 要： | 由于在分析高速履带车辆扭杆弹簧疲劳寿命的过程中传统方法采用静态最大载荷计算不能考虑动态载荷的影响，以多柔体动力学和有限元模态应力分析法为分析手段，通过数值仿真计算得到不同载荷作用下履带车辆扭杆弹簧的应力时间历程曲线．依据Miner线性损伤累积理论，结合车辆行驶环境和行驶工况的分配比例和扭杆弹簧材料特性曲线，采用Goodman法和Gerber法2种等效应力修正方法，对扭杆弹簧的疲劳寿命进行分析和预测，其计算结果表明Goodman法比Gerber法保守，两者之间的预测结果相差约7倍．该研究为设计阶段履带车辆关键零部件疲劳寿命预测提供可行的分析方法．

| Abstract: | In the analysis on fatigue life of torsion bar for high-speed tracked vehicle,the traditional methods use the maximum static load computation and can't consider the effect of dynamic load.By flexible multi-body dynamics and finite element modal stress analysis method,the stress-time history curves of torsion bar under several load cases are obtained for tracked vehicle through numerical simulation computations.According to the Miner damage cumulative theory,the fatigue life of torsion bar is analyzed and pr... |
