Parameter Sensitivity of Setback Arming Device Based on Orthogonal Experimental Design
In order to carry out the optimization design and performance study of silicon-based MEMS setback arming device,on the basis of the combined method of orthogonal experiment and finite element simulation soft-ware,six design parameters,tooth height,tooth width,spring wire width,lock beam width,lock hook spac-ing,and initial distance between teeth,were selected.The influence of these parameters on the displacement and stress of the setback arming device under normal launch and duty drop load was analyzed by parameter sensitivi-ty analysis.Through range analysis and analysis of variance,the influence of various parameters of setback ar-ming device on the structure under different shock loads was quantitatively given.The results showed that the influence of tooth height was the most significant,which was the most important factor affecting the displace-ment and stress response of setback arming device,and the initial distance,spring line width and tooth width were the secondary factors affecting the maximum displacement of service drop.Other factors did not show sig-nificant displacement and stress under normal launch and drop environment.The method proposed in this article quantitatively determined the impact of different design parameters on the silicon-based setback arming device with relatively few test runs,providing a certain reference value for the optimization of multi-parameter dual-ob-jective silicon-based setback arming devices.
