| 摘 要： | 控制臂作为汽车悬架系统的导向和传力元件,其锻造工艺复杂,在实际锻造生产过程中容易在零件的大拐角处出现穿透性的裂纹。该文用数值模拟预测金属成形过程,首先建立了控制臂三维数值模型,根据控制臂零件的几何形状设计了锻造工艺,然后对弯曲和开式模锻成形过程进行了分析。结果表明,该成形工艺可以较好地成形此零件,为该锻件的生产提供了理论依据。

| Abstract: | The forging process of the control arm,which is served as the guide and force element of vehicle suspension system,is complex.In the practical forging production,penetrated crack may appear in the big corner of the part easily.Numerical simulation was adopted to predict the metal forming process in this paper.The 3D model of the control arm was built,and the forging process was designed based on the geometry of the control arm.Then bending and open die forging processes were analyzed.The result shows that t... |
