The common methodology to design and calculate the load-deflection curve of diaphragm springs is to use the traditional Almen-Laszlo equations.However,according to the diaphragm springs designed by those equations,we can find large bias between formula values and experimental values.Based on non-linear finite element method(FEM),this paper adopts a plate-shell element building model to calculate the traits of load-deflection of diaphragm springs,analyzing the differences between the calculated values of FEM and equations.In the meanwhile,due to the measured values acquired from our equipments,we compare the bias between these two calculated values.The results demonstrate that the bias among the calculated values of FEM is smaller and also closer to the actual relations of load-deflection relation of diaphragm springs.
