用加速度传感器测量振动位移的方法
说明： 介绍了一种用加速度传感器测量振动位移信号的方法。 该方法采用频谱转换法，首先将加速度谱转换成位移谱，再计算出位移谱中每个频率分量对应的幅值 、圆频率和初相角，最后对各位移分量进行叠加得到振动位移的时间历程。 验证试验结果表 明该方法 可行 ， 精度可满足工程 实践的需要 。(A method of measuring vibration displacement signal with acceleration sensor is introduced. In this method, the acceleration spectrum is first converted into displacement spectrum, and then the corresponding amplitude, circular frequency and initial phase angle of each frequency component in the displacement spectrum are calculated. Finally, the time history of the vibration displacement is obtained by superimposing each frequency component. The test results show that the method is feasible and the accuracy can meet the needs of Engineering practice.)
