压电式加速度计和压电式力传感器都是利用压电元件的压电效应制成的传感器。已有不少文献与书籍对此类传感器工作的力学过程进行了分析,但多采用根据简化的力学模型建立微分方程分析的方法。这种方法会因引入的自由度数目增加而计算繁琐。同时,在实际的振动测试中,压电式传感器在不同的使用环境下,影响误差的因素各不相同。因此若不把传感器本身、它的安装以及被测结构的特 Piezoelectric accelerometers and piezoelectric force transducers are sensors that make use of the piezoelectric effect of a piezoelectric element. Many documents and books have analyzed the mechanical process of such sensors, but most of them use the simplified mechanical model to establish the method of differential equation analysis. This method can be computationally cumbersome as the number of degrees of freedom introduced increases. At the same time, the actual vibration test, piezoelectric sensors in different environments, the factors that affect the error vary. So if not the sensor itself, its installation and the structure of the test
