The special nonlinear stiffness characteristic of canted coil springs is the key to be widely used in high voltage power connection and high performance sealing equipment. In this paper, the theoretical method for calculating the stiffness of canted coil springs was established with the parametric modeling idea, taking single canted coil springs as an example. And through the parametric analysis of the structure of canted coil springs, the influence of each parameter on the structural stiffness was obtained. The present method for calculating the stiffness of canted coil springs is more efficient than the finite element method, and is of great significance in deepening the cognition of the nonlinear mechanism of canted coil springs, thus providing a theoretical guidance for the optimization design, production and testing of canted coil springs
