Elastic load-displacement predictions for coned disc springs subjected to axial loading using the finite element method

Abstract

The elastic load-displacement analysis of coned disc springs using the finite element method (FEM) is presented. The analysis considers the geometrical non-linearity of such springs within the working range using 8-noded isoparametric elements. The springs are analysed for a uniformly distributed axial load around the upper inner boundary with the lower outer boundary constrained vertically and other edges kept free. Verification of the present technique is obtained by analysing reference problems. Good correlation between the computed results and referenced data can be drawn.
