To calculate the contact pressure of friction pair, a 3-D finite element friction model of sintered bronze is established by simplifying the structure of clutch. Accurate contact pressure distribution of friction pair is obtained by the study of friction characteristics. The distribution results and main reasons of contact pressure are analyzed by evaluating the data of radial and circumferential directions. To verify the computation and confirm the contact pressure dynamic change under sliding friction condition, the dynamic friction element contact pressure experiment is designed. The experiment is based on the strain measuring technology, the measurement points are calibrated, the strain data is collected and the pressure curves are drawn. The simulation and experimental results show that the friction pair contact pressure is uneven on radial and circumferential directions. Radial direction distribution is influenced by loading structure. The influences of circumferential direction are elasticity modulus, groove and roughness etc. Dynamic measurement curves of contact pressure show obvious cyclic quality. Contact pressure tends to be more uniform along with load increase.
