Abstract

An improved computation of the load-displacement prediction for a coned disc spring is proposed. This work is an extension work of the previous proposed energy-based computation for coned disc springs. To show the validity of the improved method, the load-displacement results using the improved computation, the previous proposed method, and the finite element analyses are compared. In this work, the improved computation and the finite element analyses have accounted for the radial deflection of the disc spring in the form of energy method. This is different in the previous work where the radial deflection of the disc spring was ignored and the comparison to the finite element analyses without accounting the radial deflection is not practical. The present work makes the comparison to the finite element analyses to be more reasonable and more practical.
