Abstract

In order to investigate the structural stress dependence on the load conditions and material parameters, reduce and optimize the design variables, an orthogonal numerical test method is presented. First of all, the oxygen decompressor stress sensitivities to pressure, inertia force, elastic modulus and Poisson’s Ratio are analyzed based on the method. The results show that besides the effects of the pressure and the inertial force controlled by environmental load conditions, the effect of the elastic modulus on the stress is greatest; Then, the elastic modulus of the spring cavity, shell and screw are optimized by the optimization, and the optimal combination of elastic modulus for minimum stress is obtained. The conclusion shows that: the method used in this paper has a small amount of calculation, and can meet the requirement of the engineering design.
