## ANSYS6061铝合金螺柱与高强铝合金板螺柱焊过程数值模拟

Title High-strength 6061 aluminum studs and stud welding of aluminum alloy plate numerical simulation
Abstract
This paper uses a three-dimensional finite element method with high-strength 6061 aluminum stud stud welding aluminum plates were modeled using ANSYS software and finite element numerical simulation of temperature field and stress field of welding joints, the welding process temperature field and changes in the distribution of stress field to do a detailed analysis to the selection and optimization of welding parameters provides a theoretical value, help to curb the weld interface reactions. In this paper, high-strength 6061 aluminum and aluminum alloy plate stud stud welding, for example, in finite element analysis, the accuracy and completeness of the results sought, taken various effective measures and methods, the results obtained with the final compared to the extent consistent with the measured results reached up. Completion of the thesis can provide more effective methods and data to the plate with a large diameter high-strength  aluminum and aluminum alloy plate stud stud welding parameters selected, you can save a lot of manpower, material and time for future engineering and manufacturing.
