Abstract
With space-based adaptive performance of lower stiffness and greater deformation energy, the plane supporting spring finds its wide application in fields like aeronautics, astronautics, etc. In the current study, the radial stiffness formula of a single Archimedes spiral plane supporting spring is derived by means of energy approach, with three key parameters of the supporting spring as independent variables. A series of the supporting spring FEA models are established via APDL speedy modeling. According to the isolation requirements of electronic equipment for a fighter, an example is presented in the form of finite element analysis. The theoretical calculation and analysis data are studied and fitted by MATLAB using the least-square method to obtain the discipline of the radial stiffness of single spiral plane supporting spring with the changes of its three key parameters. The validity of energy-based radial stiffness formula of the spring is confirmed by the comparison between the theoretical calculation and finite element analysis results.
