Abstract
This paper describes the development of a new method to evaluate dynamic behavior and stress for durability simulations of metal pushing CVT V-belts undergoing high rotational speeds. The explicit finite element method typically used in crash analysis is adopted to simulate the high rotational speed range. A finite element model of the complete metal pushing V-belt including the layered bands is constructed where the torque is transmitted by the friction of the contact surface. In the simulation, the rotational speed gradually increases from zero to the target speed. As a result, it is possible to predict the belt stress in the high speed range and as this stress correlated with the test results, belt durability can, for the first time, be judged. To make this simulation more accessible to designers, customized pre-and post-analyzing tools were developed that enable the quick creation of new belt models.
