Characteristic research on bending elasticity of prestressed cylindrical helical spring

The property of bending elasticity deformation for prestressed cylindrical helical spring was studied. Through carrying out force bearing analysis on the spring ring and utilizing the correlated theory of mechanics of materials, the relationship between bending moment and bending angle was derived while the spring was subjected to the action of bending moment. The computation formula of bending angle of spring was obtained, and an optimization was carried out on the parameters. Through experimental verification, it is shown that the being put forward formula has a rather high accuracy, and could satisfy the requirements of engineering design, thus laid a foundation for the following-up study on the dynamics property of spring system, and at the same time provided certain theoretical basis as well for the design of new springs.
