Abstract

Abstract: Nonlinear dynamic analysis of rotating machinery system has always been the hot spot of the rotational dynamics research. This article sets up a rotating machinery condition monitoring system to realize the measurement of system dynamic characteristic parameters based on NI(National Instruments) virtual instruments technology. The measurement of vibration signal of rotating machinery system is achieved by using NI company general data acquisition module of NI Company. Meanwhile, by analyzing and processing the acquired data using LabVIEW 2012, the dynamic characteristics, such as .the speed of the rotating machinery system, the axis trajectory, spectrum parameters, are attained. The measurement results show that the rotating machinery condition monitoring system based on LabVIEW is easy to operate, easy to realize the function extension and maintenance, and that it can be used in the industrial engineering projects with rotation characteristics. LabVIEW as the development tools used by virtual instrument function is very powerful data acquisition software products support is one of the features of it, so using LabVIEW programming and data acquisition is simple and convenient.

基于LabVIEW的旋转机械状态监测系统的设计与实现

摘要:旋转机械系统的非线性动力学分析一直是旋转动力学研究的热点。本文建立了一个基于NI(National Instruments)虚拟仪器技术的旋转机械状态监测系统，实现了系统动态特性参数的测量。利用NI公司通用数据采集模块实现了旋转机械系统振动信号的测量。同时，利用LabVIEW 2012对采集到的数据进行分析和处理，得到了旋转机械系统的转速、轴线轨迹、光谱参数等动态特性。测试结果表明，基于LabVIEW的旋转机械状态监测系统操作简单，易于实现功能扩展和维护，可用于具有旋转特性的工业工程项目。LabVIEW作为虚拟仪器所使用的开发工具，功能非常强大的数据采集软件产品的支持是它的特点之一，因此使用LabVIEW进行编程和数据采集是简单方便的。
