This paper presents a method that permit to estimate a map of the power losses for any multi-pulley poly-v belt transmission. First, the work identifies and models the power losses in a simple two pulleys poly-v belt transmission, it focuses on the belt losses due to: the rubber hysteretic behavior, and the pulley-belt slip. The model developed is general so that it can be applied to any belt transmission. Finally, the developed model is extended to simulate the power losses of a multi pulley transmission such as a front engine accessory drives.
