Abstract：By analyzing friction disk surface structural characteristics and using theory of contact mechanics,a micro-normal unit contact mathematic model of thermal distortion friction pairs was built. Using mathematic statistics and normalization,the micro-model could be transferred to macro-mathematic model,and then the normal elastic contact characteristics of friction pairs could be obtained. When the Kelvin-Voigt (KV) model was inputted into elastic contact characteristics,viscoelastic contact differential operator was included in the equation,and viscoelastic contact mathematic model that included the relation of stress to strain was built. So colligating above all the simulation results,an axial vibration mathematic model was built,and the vibration characteristics was obtained by simulation. For verifying simulation results,axial vibration experiment of friction pairs of clutch was tested on conditions of various rotational speeds. The contrasted results show that model precision is 87%,and the simulation results are correct. This is significant in theory and engineering design,and promotes studying deeply on vibration characteristics to advance friction pairs serviceability and life.
