The dynamic behavior of a metal CVT belt was calculated under the conditions of the lowest pulley ratio of a 2-liter class unit and high input torque by using 3-D finite element analysis (FEA) simulations. The calculated results were then used to analyze the torque-transmitting mechanism of the metal CVT belt. As a result, it was found that 62% of the input torque was transmitted by the compressive force of the elements and 32% by the tensile force of the bands. It was also revealed that the slip velocity between the primary pulley and the elements contributing to the compressive force between the elements was in a range of 500-1,000mm/s in the angle of contact on the primary pulley.
