【Abstract】 Taking the effects of circumferential curvature of the wave spring and curvature of wave shape into consideration, in this article a theoretical calculating model based on mechanical properties of the wave spring was presented by applying principle of virtual work and Moore Theorem. By using this model, the relation of load and displacement was solved. Meanwhile a finite element analysis model was also established, so that an analytical comparison of calculation results of the two models could be conducted to make sure the validation of the theoretical model. With this calculating model, the methods of improving carrying capacity of the spring were present.更多还原
