| 摘 要： | 介绍了一种基于Abaqus显式算法的计算方案来预测车轮在按SAE J175的规定进行车轮冲击试验过程中的车轮碰撞性能.为节省计算时间,赋予碰撞体一个撞击初速度代表其自由下落过程的最终状态,并采用了质量缩放法.以等效塑性应变作为损坏指标判定车轮是否通过动态冲击测试标准.仿真结果得到实例的验证,并表明车轮的塑性变形主要集中...

| Abstract: | A numerical procedure using Abaqus/Explicit is presented to predict the impact performance of wheel during its impact test conducted as per the provisions in SAE J175.In an effort to save computation time,the striker is assigned an equivalent initial impact velocity to represent its end state of free-fall process,with a mass scaling method also adopted.The equivalent plastic strain is used as the damage indicator to judge whether the wheel should pass the impact test.The simulation result is verified in a r... |
