By means of large-scale analysis software ANSYS, a finite element model of elastic plastic axial symmetry contact problem is established which remained with the nonlinear surface and the nonlinear materials for the connecting of composite material bolt threaded nut. Stress-strain field has been calculated under the axial load with gap coordination of the composite material bolt threaded nut. The results indicate that, the joint of the composite material bolt threaded nut can satisfy the intensity and the rigidity request for the coal mine safety production. The researches in the paper have provided theoretical basis for the design of connecting the composite material bolt thread nut, and have important significance for widely using of the composite material bolt thread nut in project.
