为满足机械工程测试技术实验教学的需要,采用虚拟仪器技术,基于LabVIEW平台,开发了虚拟仪器教学实验平台。解决了在《机械工程测试技术》课堂教学过程中普遍存在理论教学抽象、实验设备陈旧、功能单一,缺乏创新等问题。基于该平台,已开设了频率混叠和采样定理、波形的合成与分解、振动信号的动态测试与分析等典型实验,取得了良好的教学效果。
In order to meet the needs of experimental teaching of mechanical engineering test technology, the virtual instrument technology was used to develop the virtual instrument teaching experiment platform based on LabVIEW. It solves the problems of theoretical teaching abstraction, outdated experimental equipment, single function and lack of innovation in the teaching process of Mechanical Engineering Testing Technology. Based on this platform, typical experiments such as frequency aliasing and sampling theorem, synthesis and decomposition of waveforms, dynamic testing and analysis of vibration signals have been carried out and good teaching effects have been achieved.
