Abstract
The paper presents an experimental stand that simulates the running of a hybrid car. The important piece of the stand is a mechanical system which includes a planetary mechanism. It engages a heat engine, a three-phase asynchronous electric motor and a power alternator. The stand was designed to be mounted on a roller stand and a stand with electric brake. The mechanical system design was made in the CAD soft, which has facilitated the rapid achievement of the geometrical and mechanical measures necessary to simulate the mechanism functioning with two degrees of mobility that engage the three sources of power. The simulation was done with a computer program that allows solving the machine differential equations of motion. Previously there were presented the mechanism equations of motion with two degrees of mobility that engage the three sources of power. In the end are presented the conclusions derived from the numerical and experimental measurements.
