摘要

合理的结构参数组合可提高加速度传感器壳体结构的固有频率

保证传感器在振动环境下输出信号稳定。通过建立竖直薄板力学模型

确定影响加速度传感器壳体固有频率的结构因素。基于响应面法思想

利用试验设计的方法

以加速度传感器壳体固有频率为指标

各结构参数为因素

设计二次回归正交旋转组合试验。通过ABAQUS6.10软件建立各组试验结构参数组合下的分析模型并提取固有频率

最终确定使固有频率维持在较高水平的结构参数组合区间。通过对优化后参数进行验证性试验

Abstract

Reasonable structural parameter combination can improve natural frequency of shell structure of acceleration sensor

ensure output signal stable in vibration environments.Through building mechanical model for vertical plate to determine structural factors which impact natural frequency of acceleration sensor shell.Based on idea of response surface method

use design of experiment（DOE） methods

use natural frequency of acceleration sensor shell as an index and use each structural parameter as factor to design the quadratic regression orthogonal rotation combination experiment.Structural parameters of each group of test combined analysis model is set up by using ABAQUS 6.10 software and extract natural frequency

finally determine structural parameter combinations interval which makes natural frequency maintain at a higher level.Through confirmatory test on optimized parameters

the results show that natural frequency of acceleration sensor shell after optimizing interval of random structural parameter combinations can reach above 10 kHz.
