Proposed MEMS safety mechanism shows robust performance in drop and firing tests, suggesting reliable integrated design.
In response to the requirement for the integrated design and manufacturing of non-silicon MEMS safety and arming devices, a MEMS setback safety mechanism with an integrated design is proposed. Its movable parts are electroformed synchronously with the substrate, having the same thickness and eliminating the need for assembly. The dynamic characteristics of the setback safety mechanism with a dislocation-type sliding tooth structure are simulated and analyzed, and the structural parameters of the sliding teeth are determined. The test results show that after the drop test of the integrated setback safety mechanism, the mechanism does not deform and can meet the requirements of drop safety; after the firing test of a 35mm grenade, only one prototype has a failure of the setback spring breaking, and all the setback safety mechanisms can be armed. It basically meets the usage requirements, verifying the feasibility of the integrated design and manufacturing.
