摘要
应用ABAQUS软件对TC4合金高尔夫球杆头本体部分超塑胀形进行仿真,分析了不同加载路径、不同摩擦系数以及不同应变速率对壁厚分布的影响,着重分析了上述不同情况下危险点的壁厚随时间的变化规律。结果表明,采用合理的加载路径、低的摩擦系数以及高的应变速率敏感性指数m值可以很好地改善成形件的厚度不均匀性,提高成形件危险点的壁厚。试验验证了仿真和试验结果比较吻合。
The commercial software ABAQUS was used to simulate the superplastic bulging process of golf club head body of TC4 alloy, the influences of loading routes, friction coefficients as well as strain speed on the thickness distribution were analyzed, the change law of thickness distribution in the hazard point with time on the above different situations was emphatically analyzed. The results indicate that using the reasonable loading route, low friction coefficient and high m value can improve the uniformity of the thickness distribution, and can enhance wall thickness in hazard point.The experimental verification indicates that the finite element simulation data tallies comparatively with results of practical test.
