On the Influence of Friction in the Calculation of Conical Disk Springs

18 Apr.,2023


An analytical solution is proposed by the authors in order to take into account the effects of friction in the calculation of conical disk springs. The new formulation allows a more accurate estimate of the load corresponding to a given displacement, but it implies the knowledge of the friction coefficient f between the spring and the supporting surfaces. The reported numerical examples show that, disregarding friction effects, the maximum error committed in the evaluation of the load is in the range 2–5%, with f = 0.14 (average friction coefficient value determined experimentally on commercial conical disk springs with different geometry). Comparison with both experimental and finite element calculations show a very good agreement of the analytical prediction.
