便携式微弱振动加速度测量系统

Portable Accelerometer for Micro-vibration Test System

为提高现有的加速度传感器的灵敏度 ,采用专用电荷放大器 ,同已有的数据采集器和测量分析软件集成 ,组成了便携式“微弱振动信号加速度测量系统”。实践表明 ,本系统能对微弱的振动加速度进行现场测量 ,满足测量技术要求 。

To improve the sensitivity of the exiting accelerometer, an exclusive charge amplifier is integrated with a data sampler and analysis software, forming a portable micro vibration test system. Experiments show that the system can be use in field measurement of the acceleration of micro vibrations with a reasonable accuracy.
