| 摘 要： | 电磁成形过程中,成形线圈受应力场、温度场及电磁场综合作用。采用有限元分析软件ANASYS进行磁场-温度场,磁场-应力场耦合分析,综合考虑应力、载荷条件与疲劳强度系数等疲劳影响因素,基于线性累积损伤理论和随机Miner准则,使用Fatigue Tool疲劳分析工具对线圈进行疲劳寿命估算,并根据分析结果对线圈结构参数进行了改进,对比原始均匀压力线圈,改进后线圈寿命有所提高。

| Abstract: | In the electromagnetic forming process,there are combined effects of the stress field,temperature field and electromagnetic field on the tool coil.The magnetic-temperature coupled field and the magnetic-stress coupled field were simulated by ANSYS,considering the effects of the stress,loading conditions and fatigue strength coefficient.According to the fatigue stress-life method,the fatigue life of the coil was predicted by the Fatigue Tool module based on the linear cumulative damage theory and the random ... |
