摘要：
The friction stir welding is a green and efficient technology, which has been applied in the manufacturing of light alloy widely, and the temperature field analysis is the basic of studying the microstructure and property, welding deformation, and residual stress of weld; therefore, the orthogonal ridgelet finite element method combing the traditional finite element method with orthogonal ridgelet transform is constructed to analyze the temperature field of friction stir welding. Firstly, research progress of friction stir welding and wavelet finite element method is summarized. Secondly, the basis theory of orthogonal ridgelet transform is analyzed. Thirdly, the orthogonal ridgelet finite element model for analyzing temperature field of friction stir welding is constructed. And then the heat source model of friction stir welding is constructed. Finally, temperature field simulation of friction stir welding based on orthogonal ridgelet finite element method is carried out, and the temperature-changing rules of friction stir welding are obtained. The effect of slip factor and rotating speed of stir-welding head on peak temperature field of friction stir welding are obtained. Results showed that the orthogonal ridgelet finite element method can analyze the temperature field of friction stir welding effectively.
