【Abstract】 In this paper, we have performed a numerical analysis on multi-hole rectangle structure of Si capacitor microaccelerometer base on its numerical model. Based on the comparison of the analysis results, we discussed how the structure influences the damping characteristics of the whole system, and analyzed the turbulence of this kind of structure. We identified the structure value when we can get physical similar cells from the whole sensor mass. All these work help us get the formula of damping characteristics of,multi-hole rectangle structure, also help us design the capacitor microaccelerometer and optimize its performance.更多还原
