摘　　要：针对传统振动测试方法的不足,运用图形化编程语言LabVIEW设计了远程振动参数测试及动态特性分析系统。实现了对振动物体加速度、速度、位移信号的实时处理、显示以及频谱分析。通过样条插值得到了振动系统幅频特性曲线,在此基础上完成了固有频率、阻尼比等动态特性参数的估计。同时利用Data Socket技术实现了基于网络的远程自动测试。In view of the faults of traditional vibration measurement, the system of remote vibration measurement and analysis of dynamic characteristic was designed based on the graphical programming language LabVIEW. The acceleration, speed, displacement signal of vibration was processed, displayed real time and its spectrum was analyzed. The amplitude-frequency characteristic curve diagram of vibration system＇ was carried out by spline interpolation and then the parameters of dynamic characteristic, such as inherence frequency, damp etc, were gained. At the same time the remote automatically measurement based on network was achieved by make use of Data Socket.
