在航空及其他国防工业的测试技术领域里,振动冲击过程的测试是一个重要课题。对于脉冲作用时间较长(100毫秒以上)、频谱范围较低(几十赫芝以下)的振动冲击量,常用压电晶体式加速度计测量,但不能测量波形的直流分量,无法正确反映振动冲击过程的全貌,它的使用受到限制。张丝式加速度计是一种非粘贴式应变传感器,能够测量波形的直流分量,有较好的动态特性,比较适宜于作用时间较长、频谱范围较低的振动冲击过程
In the field of testing technology for aviation and other defense industries, the testing of the vibrational impact process is an important topic. For long pulse duration (more than 100 milliseconds), low frequency range (dozens of Hertz below) vibration impact, commonly used piezoelectric crystal accelerometer measurement, but can not measure the DC waveform of the waveform, can not correctly reflect the vibration impact The whole picture of the process, its use is limited. Zhang silk accelerometer is a non-stick strain sensor that can measure the waveform of the DC component, has better dynamic characteristics, more suitable for longer-acting, low-frequency spectrum of the vibration impact process
