Abstract
AbstractA simulation model has been developed to determine the behaviour of power transmission of a metal pushing V‐belt CVT at steady states. This allows to calculate the characteristics of forces and permits to evaluate the necessary pulley thrust, the maximum transmittable torque and the efficiency. Therefor the pulley and shaft deflection and the unilateral constraints of contacts must be modelled properly. The dynamics of the belt is specified by separate longitudinal and transversal approaches. The transversal dynamics is modelled continuously applying a Ritz‐approach based on B‐Splines. The longitudinal dynamics is described with Lagrange coordinates. So discontinuous effects as separation of elements can be modelled by continuous shape functions. Concluding, the obtained results of the presented simulation model are compared with measurements published by Doshisha University [2].
