基于ANSYS的异种材料堆焊温度场动态模拟

针对大多数堆焊温度场的数值模拟都是应用于同种材料的现状，对异种材料的堆焊温度场进行了研究.建立适当的有限元模型，对异种材料堆焊过程中温度场的瞬态变化进行了动态模拟.利用三维有限元网格划分技术，对工件进行网格划分，并采用网格自适应技术对焊缝金属的网格进行自动加密与生成，为缩短焊接过程数值模拟创造了条件.在此基础上，利用ANSYS软件的APDL语言编写程序，实现施加移动焊接热源，得到了异种材料温度场的分布规律.计算结果与焊接温度测试结果很接近，表明该计算方法能够准确地计算焊接温度场，是一种实用的工程计算方法.

Dynamic simulation of temperature field in surfacing Welding of heterogeneous materials based on ANSYS

In view of the fact that the numerical simulation of temperature field is mainly applied in the surfacing welding of homogeneous materials,the surfacing welding temperature field of heterogeneous materials has been investigated.A proper finite element model was established,and the dynamic simulation of the temperature field during surfacing welding of heterogeneous materials was conducted.With the finite element mesh generation technology,the mesh was generated for the practical component.And the mesh for t...
