Development of virtual experiment platform for the mechanical theory teaching

In order to strengthen engineering background of theory teaching of mechanical major, a virtual experiment platform based on LabVIEW for fault diagnosis of rotating machinery is developed. It can be used as engineering examples demonstration in theory teaching. Additionally, It can be connected with testing system through the interface of NI-DAQ to complete mechanical fault simulation, acquisition and analysis of experimental data and intelligent fault diagnosis of machinery. The virtual experiment platform is developed to simulate typical fault of rotating machinery, such as rotor fault, rolling bearing fault and gear fault. And because the principle of this platform involves the knowledge of many theory courses it is very useful to assist teaching and also convenient to experimental research for students as a second-development platform.
