Abstract
Planar spring adopted in micro inertial devices is usual y in the form of S-shaped and equal line-width. When the planar spring works under inertial loads, its elastic coefficient is not easily calculated theoretical y. It is deduced based on mechanical energy method in this paper. And further, this paper designs the S-shaped gradient line-width spring and deduces the theoretical formula of the elastic coefficient. The simulation is done and the applicability of the formula is verified by using ANSYS software. The analysis demonstrates the relative error of the elastic coefficient formula is less than 3%under a concentrated force, and the average relative error is less than 5% under an inertial force. The S-shaped gradient line-width spring has abilities of the uniform deformation and stress distribution, anti-high overload. The study results provide a certain theoretical reference for the optimal design of micro inertial devices.关键词
