- Abstract:
- With the developing language of ANSYS software and the using of the double-ellipsoid heat sourcemodel, a model of two steel plate that connected by Y groove multi-layer and multi-pass CO, are welding seamis created. Three different kinds of element birth and death technology are used separately in the model. Aftcrthe comparison of three difrerent numerical simulation results, the correctness of the element birth and deathtechnology which activates the welding material step by step is validated, The temperature field distributionregularities of the welding at various time points of welding progress are analyzed. The cycling curves of typicalspots on different place of the model are studied. Based on the results , the component’s tissue, properties andresidual stress at different position of the model can be estimated.
