Abstract
In this paper, coupled field analysis methods in finite element analysis software are investigated. 3D mechanical modeling software Solidworks 2011 and general finite element analysis software ANSYS Workbench 14.0 are used in combination, and two sets of sequential coupling simulation schemes containing thermal-vibration sequential coupling analysis and vibration-thermal sequential coupling analysis are designed. Two schemes are mutual corroborations for thermal and vibration coupling analysis, especially using the trial calculation to connect random vibration analysis and thermal cycling analysis. The results of the real environmental test which was conducted in laboratory show the finite element simulation in this paper has been proved to be correct. Finally, the comparison analysis of the two sets of simulation schemes is given and a feasible simulation analysis method for practical engineering application is explored.
