| 摘 要： | 为探讨微机电系统中平板结构弛豫动力学特性,基于Euler-Bernoulli方程,计入空气滑膜阻尼与压膜阻尼对微板弛豫过程的影响,导出两端绞紧微板挠度弛豫表达式,并给出临界阻尼、过阻尼及欠阻尼时微板弛豫Ma-ple算例。利用ANSYS对微板临界阻尼、过阻尼以及欠阻尼弛豫进行仿真,结果显示不同长宽比微板仿真数据均与理论计算符合较好。 |

| Abstract: | In order to explore micro-plate relaxation dynamics characteristic,the deflection relaxation expression of micro-plate with two hinged ends was educed based on Euler-Bernoulli equation considering air slide-film and squeeze-film damping effect.Numerical examples of micro-plate deflection relaxation process under critical-damping,over-damping and under-damping were calculated by Maple.Micro-plate relaxation process under critical-damping,over-damping and under-damping were simulated by ANSYS.Simulation result indicates that simulation data of micro-plates with different length-width ratio conform to theoretical calculation. |
| Keywords: | Euler-Bernoulli equation micro-plate air damping relaxation |
