摘要
回顾虚拟仪器技术进步历程,介绍虚拟仪器及其系统的构成、软件开发平台以及虚拟仪器的应用,并就虚拟仪器在振动测试中信号的产生、采集、控制进行了说明。利用该系统对悬臂梁进行了振动测试,并给出了其幅频特性曲线,实验证明了测试系统的可靠性与可行性。
The history of virtual instrumental technology is first reviewed. Then the general construction of virtual instrument (Ⅵ), virtual instrumental system, the software development platform and applications of virtual instruments are described. It is also illustrated about how to produce signal,how to acquire data, how to control the vibration experiment system with virtual instruments. Using this system, we have tested a cantilever stimulated with vibration and got the amplitude-frequency characteristic curve diagram. It is proved by the final test results that the experiment system has reliability and feasibility.
