Excellent brake performance is the necessary condition to securely driving, and the friction wear property of brake disk serves a significant function in brake system. In order to acquire the parameters (normal force, friction force, rotate speed and temperature) which are used to characterize friction wear properties of brake disk, friction wear property information acquisition system based on virtual instrument technology LabVIEW is designed. Hardware of this system mainly consists of sensors utilized as acquiring information on friction wear property, as well as signal conditioning module and data acquisition card used as A/D transformation. Under the circumstance of virtual instrument LabVIEW, information acquisition and processing interface and former information query interface are programmed. Debugging results present that the designed information acquisition system can accurately acquire the demanded information, intuitively display the obtained information, and easily achieve the query of former information. Therefore, the designed data acquisition system satisfies the demand of information acquisition related to friction wear property of brake disk.
