The factors of influencing the thermal load and thermal stress at the peril point of hot forging die were analyzed. 分析了影响热锻模热负荷与危险点处热应力的因素。
Nominal stress method was been adopted to predict the fatigue life of magnesium alloy wheel by the stress of peril point. 根据强度分析确定危险点的应力值,采用名义应力法对镁合金车轮进行疲劳寿命预测。
