Virtual instrument is an outcome of modern computer software technology and communication technology in combination with test and measurement technology.LabVIEW,released by the American company of NI,is a kind of developing flat of virtual instrument with powerful function.The main characteristics of wavelet transform is that some character can well outstanding by transformation and it is an important way to study signal in time-frequency domain.Designed and carried out the test system of rub noise based on LabVIEW and wavelet transform.Using this system,can measure and analyze the rub noise,it is advantageous to understand the principium of rub noise,improve the friction condition and promote the environmental protection business.
