摘要

针对冲击测量中传感器安装块导致失真的问题,进行了分析仿真和不同安装块的冲击对比试验研究。对使用不同规格安装块的传感器冲击数据进行冲击响应谱和能量谱分析。分析和仿真结果表明,安装块对冲击测量的影响与安装块的材料、尺寸均有关,扁平型的安装块和传感器组合后整体共振频率更高,对于冲击测量没有显著影响;但常用的边长10 mm的立方体安装块及瘦高型的安装块,在5 000~10 000 Hz的高频段失真明显;试验结果与仿真结果在规律上一致。研究结果对于冲击测量安装有指导意义。

Abstract

Aiming at the problem of distortion caused by sensor installation in impact measurement, simulation and comparative tests on impact of different mounting blocks are carried out. The impact response spectrum SRS and energy spectrum ESD analysis are carried out on the measured data of sensors with mounting blocks of different specifications. The analysis and simulation results show that the impact of mounting blocks on the impact measurement is related to the material and size of mounting blocks, and the overall resonance frequency of flat mounting blocks and sensors is higher, which has no significant impact on the impact measurement. However, the commonly used cube mounting blocks with a side length of 10 mm and thin and tall mounting blocks have obvious distortion in the high frequency band of 5 000-10 000 Hz; The experimental results are consistent with the simulation results. The research results have guiding significance for impact measurement installation.
