摘　　要：介绍了YD-1型压电式加速度传感器与CZ-4型磁座构成的磁座安装测振系统的安装谐振频率。给出了磁座安装测振系统受力分析及建立系统力学模型的一般方法,计算了该系统的谐振频率,并就磁座质量及剩磁大小对安装谐振频率的影响进行了讨论。The mounting resonant frequency of vibration measurement system formed with piezo-electric acceleration sensor YD-1 and mounted magnetic base CZ-4 is addressed. The common approach to set a mechanics model of the system and analyze the force of the load on mounted magetic base in vibration measurement system are presented. The resonant frequency is calculated. The influence of mass and magnetization intensity of the magetic base on the mounting, resonant frequency is discussed.
