The article analyzes stress and strain of well-set subassembly under different load model by used FEM analyzing method. Put forward some techniques of FEM analyzing method about loading, characteristics of manual work loading and software auto- loading, influencing factors of loading for the FEM analyzing result of well-set subassembly. What about reduce influences to FEM analyzing result due to loading irrationality. Some loading techniques were made availability and one example of FEM analyzing result for the stress and strain of well-set subassembly. Finally, put forward some views and experiences availability for FEM analyzing result about of the stress and strain of flat well-set subassembly. It may have some reference worthiness for FEM analyzing researching and using technician.
