摘要
基于虚拟仪器技术应用于扭振测试领域,开发出一套转子扭振测试系统。扭振试验合同时具备转动轴和摆动轴,可用于对这两种轴的扭振问题进行研究,并可实现多种方式对扭振信号进行测试。数据采集硬件选用了高性能数据采集产品,扭振测试软件基于图形化编程语言LabVIEW开发,能够对扭振信号进行采集,并能快速高效地分析处理扭振数据,显示扭振时域与频域的波形曲线等功能。试验结果表明研制的测试系统能较精确地进行扭振测试,同时便于调整转速,布置测点位置,易于操作、安全可靠。
The virtual instrument technology is used in torsional vibration study to create a torsional vibration study to create a torsional vibration test system. There are rotational shaft and swing shaft in the torsional vibration test-bed. They are used to study the two kinds of torsional vibrations. In the torsional vibration test-bed. They are used to study the two kinds of torsional vibratious. In the torsional vibration test-bed can acquire torsional vibration signal in different methods. This system＇s data acquisition device is a high performanee data acquisition product, test software is programmed with LabVIEW software, The torsional vibration signal can be acquired, and analyzed fast and high efficiently in this system. Torsional vibration signal can be expressed in time and frequency domains. Many test results proved the precise of test results. And this test-bed is safe and reliable, it is convenient be used for testing and measuring torsional vibration.
