Stress-deformed state of cylindrical springs

Abstract

An elastic element widely used in machine engineering is spring. It is used predominantly for the amortization of impulses and shocks (for smoothing and leveling of the load in the contact zone of related details of design). The paper reviews general dependences between the deformations and transitions of springs in cylindrical coordinates. Considered task is modeled in axysimmetrical form. In solution of general equations semi-inverse method of Saint Venant is applied. Stressed-deformed state of a cylindrical spring has been studied during the action of different loads (equally distributed intensity q or fixed load p). To specify stressed-deformed state of a spring, a principle of power dependence and superposition method is used. At first, the components of stress and transitions of each power separately are defined, and then corresponding power factors (stress components from each power separately) are summarized using superposition method. The agents for designing spring construction considering existing loads have been obtained.
