A numerical model was developed to analyze the power transmitting mechanism for metal pushing V-belt CVT at steady state. The model consists of linear springs representing the rigidities of block and rings, and interface elements which identify slippage between two contacting objects. By using the present model, forces acting on the belt were calculated. Calculated results were compared with the experimental results and reasonable agreements between both results were obtained. The numerical analysis reveals that the rings are sliding in the driven pulley and transmit negative power at the speed ratio i＜1.0. Consequently, blocks transmit greater power for i＜1.0 than that for i ≧ 1.0.
