Abstract: The canted coil spring is widely used in the medical equipment, the high-voltage switch, the auto industry and other fields. Because of its special structure and complex stress state, there is no effective theoret-ical calculation method to obtain the load-displacement curves except for experimental and numerical methods. In this paper a finite element model of the canted coil spring is established on the ANSYS software platform to obtain its load-displacement curves. The relationships of the wire diameter, the pitch, the magnitude of inclina-tion of the canted coil spring with its load-displacement curve and the stiffness under a fixed load displacement condition are analyzed. The deformations of the canted coil spring under the working condition are studied. The calculation results provide a theoretical basis for the optimization design and the application of the canted coil spring.
