针对光谱仪减振架振动检测，开发了振动信号分析系统；采用图形化开发工具。本测试平台分为两个部分：硬件部分通过加速度传感器、信号调理电路和 PXIe4497数据采集卡把振动信号转换输入到计算机中；软件部分利用 LabVIEW平台实现数据采集及分析的功能，从时域、频域和时频域角度对其进行特征提取。测量时最大的误差为 3.327%，处于正常实验测量误差。

A vibration signal analysis system was developed for vibration detection of the spectrometer vibration damper. The graphical development tool was used to this end. The system consists of hardware and software. The hardware converts the physical vibration into digital signal and sends it into the computer through the sensor, signal conditioning circuit, and data acquisition card. The software uses the LabVIEW platform to realize the functions of data acquisition and analysis from the time domain, frequency domain, and time frequency. Feature extraction is executed from the domain angle. The maximum error of measurement is found to be 3.327%, which is within the normal measurement error.
