本文提出了压电式阻抗头的简化力学模形,用机械阻抗的方法分析,清析地表达了压电式阻抗头在机械阻抗测量中的力和运动的传递过程并导出它的力的测量误差和加速度测量误差表达式
In this paper, a simplified mechanical model of the piezoresistive head is presented. By means of mechanical impedance analysis, the force and motion transfer process of the piezoresistive head in the mechanical impedance measurement and the derivation of its force are clearly expressed Error and acceleration measurement error expression
