摘要
运用Ansys软件对轮毂的13°冲击强度进行分析。结果表明,轮毂正面最大应变量为5.964%,背面最大应变量为2.917%,都小于规定的正面8%和背面6.2%的应变量,符合冲击强度要求;旋压轮毂实物在13°冲击试验机上试验结果与仿真得到的冲击强度结果可以相互印证。另外,轮毂13°冲击仿真可以发现轮毂受冲击时易产生裂纹的危险区域,对轮毂结构优化有重要意义。
The impact fatigue strength of the wheel hub at 13° was investigated by using Ansys software.The results show that the maximum dependent variable is 5.964% on the front of the hub and 2.917% on the back.Both are less than the specified8% on the front and 6.2% on the back,meeting the impact strength requirements.The impact test results of spinning wheel materials in 13° tester,and the results of simulation for the impact strength can support each other.In addition,the 13° impact simulation can find danger zone of wheel hub which is easy to crack,it is very important for hub structure optimization.
