Gas mask part assembly process analysis method

The invention provides a gas mask part assembly process analysis method. By using a finite element method, the gas mask part assembly process is subjected to simulation analysis, and the simulation process comprises three parts of pretreatment, solution and aftertreatment. Pretreatment mainly comprises introduction of a gas mask part three-dimensional model, building of a rubber cover body material model, dividing of computing grids and setting of contact conditions; during solution, firstly boundary conditions and loads of the model are set, and then a parallel operational model of a computeris utilized to solve the model; during aftertreatment, characteristics of a simulation result are extracted, and a graph is drawn and analyzed. By means of the gas mask part assembly process analysismethod, deformation and stress of the gas mask super-elastic material in the assembly process can be obtained, and the reliability of assembly of the gas mask is evaluated. 本发明提出种防毒面具零部件装配过程的分析方法，本发明是有限元方法对防毒面具面罩零部件装配过程进行仿真分析
