摘要

针对高冲击测试只校准加速度传感器而忽略其安装方式可所致测试误差，分析高冲击加速度传感器灵敏度横向效应产生原因与测试仪整体力学模型。通过Hopkinson杆冲击实验装置对传感器每轴横向效应实验分析，利用ANSYS软件分析测试仪在冲击加速度载荷20000 g时结构响应。结果表明，测试仪结构发生振动时传感器装配方式所致测试误差不可忽略。

Abstract

It is common that only the accelerometer is calibrated in high impact test, so the measurement error caused by the accelerometer assembling is neglected. First, analyzes the reason transverse effect arise and the instrument overall mechanical model. Use Hopkinson bar to do the impact test on each axis of the accelerometer to study the transverse effect. And then use ANSYS to analyze the instrument structural response under the load of 20000g acceleration. The results show that the instrument mechanical shell vibrates and the measurement error caused by assembling of the accelerometer cannot be neglected.
