Nyashin Yu.I., Osipenko M.A., Gitman M.B. Equal-stress leaf springs

Abstract

A series of results concerning the finding of the parameters of the equal-stress leaf springs is presented. The nonlinear bending of the single-leaf spring of the variable profile is considered. It is established that the optimum profile for a strong bending is elliptic. The linear bending of a two-leaf spring with leaves of a variable profile is studied. It is proved that the equal-stress spring does not exist for different lengths of leaves, if the stresses sign is invariable along leaves. Such spring exists only for equal lengths of leaves. If the sign varies but the absolute value of stress is invariable, then the equal-stress spring exists when a shorter leaf is sufficiently long. Such spring contains the internal joint. The parameters of a partially equal-stress two-leaf spring with constant profiles of the leaves are found. The connection between these parameters and a solution of the problem of maximum stress minimization is established.

Keywords
