| Abstract: | The configuration of hardware that composes virtual instrument is presented. The working principle of VXD in virtual instrument based on windows platform is discussed. The dynamical model of jump vibration is built, the nonlinear dynamical characteristic of jump vibration is studied and find the sub-harmonics vibration is main characteristic. A virtual instrument based on WS-I42008 data acquisition board and PC-DAQ mode is developed for vibratory rollers fault diagnosis and condition monitoring, and is used successfully in practical application to monitoring jump vibration to prove that this virtual instrument is valid and reliable. |
| Keywords: | virtual instrument jump vibration sub-harmonics condition monitoring |
