N2 - Micro springs are often served in the fuze's MEMS-based safe and arm systems as force and energy transmission elements, which are critical to guarantee the fuze safe and arm systems' safety in normal time and proper function after launching. While the micro springs are easy to get buckled under pressure thus influence the normal function, to avoid that, the relationships between the critical buckling pressure and the structural parameters were taken into consideration in the design process. Taking the S-shaped micro spring as example, models were built using modeling software Inventor and eigenvalue buckling analysis was performed with the FEM (finite-element method) software ANSYS, hence the relationships between the critical buckling pressure and the structural parameters of the micro spring in certain conditions were obtained.
