【摘要】 在测量冲击加速度信号时,加速度传感器的安装方式对测量精度有一定影响,本文利用频域建模法、频域插值法以及时域建模法结合逆滤波技术对测量的畸变加速度信号进行修正,使重建后的信号更加逼近真实的加速度信号。详细探索了三种方法的基本原理,并在MATLAB环境下进行了信号重建的仿真研究,获得了相关有价值的认识。更多还原

【Abstract】 In the measurement of the impact acceleration signal,the installation mode of acceleration sensor has some influence in the measurement accuracy.To make the recontruction signal is more approximated to actual signal,combined with inverse-filtering technique,frequency-domain correction、frequency-domain interpolation and time-domain modeling methods are used to reconstruction actual signal from distortion acceleration signal measured in test are introduced in detail in the topic.The basic principles of these three methods are researched in detail,and simulation research of acceleration signal reconstuction based on Matlab is worked,some valuable related knowledge has been obtained.更多还原
