Wear life prediction

wear condition monitoring and op timal design of the parameters are three difficulties in wear studies. Based on the discrete mathematics and computer science

a numerical simulation model of a rubbing system of plat- bottomed cam follower is established. By introducing the concepts of position vector and wear step

the continuous wear process is discr etized

thus realizing the wear life prediction of the cam and the dynamic simul ation of the movement rule of the follower.
