摘要
根据实际工况确定轮胎模具弓形座力学计算式,通过CAD/CAE及疲劳寿命分析软件模拟分析不同上部悬臂厚度和材料的弓形座疲劳寿命和安全因数。结果表明:上部悬臂厚度增大,弓形座疲劳寿命明显延长和安全因数明显增大;40Cr材料(钢)弓形座的疲劳寿命长于和安全因数大于QT450-10材料(球墨铸铁)弓形座。
The mechanics calculation formula of tire mold slider was determined according to the actual working condition.The fatigue life and safety factor of slider with different upper cantilever thickness and material were simulated and analyzed by CAD/CAE and fatigue life analysis software.The results showed that the fatigue life of the slider was significantly prolonged and the safety factor was significantly enlarged as the thickness of the upper cantilever increased.The fatigue life of the slider made of 40Cr material was longer than that of the slider using QT450-10 material,and the safety factor of the 40Cr steel slider was also bigger.
