中文摘要：
采用计算机、数据采集卡、信号转接板等硬件与在LabVIEW虚拟仪器平台上开发的软件构成了一套完整的振动测试分析系统．振动分析的精度问题是振动测试的关键，为了解决这一问题．系统采用了相位差校正法进行频谱校正．文章还从硬件和软件功能两方面对测试分析系统的实现方法及功能进行了详细的介绍．实验表明，该系统具有测试精度高、抗干扰能力强、检测精度高、操作简单等优点．
英文摘要：
The research of vibration measurement and analysis system consisting of computer, data acquisition board, signal modulate board and software developed by LabVIEW virtual instrument technology are introduced. In vibration analysis instrument, precision is the pivotal part. In order to improve the precision of analysis,System uses phase difference correction,a reasonable and efficient spectral correction to correct the frequency spectrum. The function and its realization of the system from the hardware and the software are also introduced. It is proved by test that the system has high precision, strong anti-interference, high efficiency and convenience manipulating.
