A numerical model was developed to analyze the power transmitting mechanisms for a metal pushing V-belt type CVT at steady state. The model consists of linear springs representing the rigidities of blocks and rings, and interface elements which identify slippage between two contacting objects. By using this model, forces acting on the belt were calcultated. Reasonable agreement between the calculated and experimental results was obtained. The effect of coefficient of friction on the thrust ratio was also analyzed. It was revealed that the thrust ratio becomes larger with an increase of the coefficient of friction.
