Study on the Characteristics of Acoustic Emission Signals of Slider-disk Contact

Lin Jing Meng Yonggang(State Key Laboratory of Tribology,Tsinghua Univeraity,Beijing 100084,China)  
The characteristics of the acoustic emission(AE)signals of slider-disk interface under different conditions of slider flying were investigated.The frequency components of the AE signals were analyzed.The AE signals generated only by the vibration of the slider suspension was compared with the AE signals detected under contact,showing that the AE signal generated by the slider suspension vibration is closely related to the contacts between slider and disk,which is an important source of AE signals during the contacting between the slider and disk.The AE signal generated by the slider suspension vibration can be used to detect the contact between the slider and disk,so that to improve the detecting sensitivity.
