All parts of the complete DynoTrain family fit into different test applications. This results in a flexible system for different applications and guarantees that the investment is secured. Together with the DynoPrime, the energy runs in a loop and only the losses of the system have to be supplied from the grid. • R&D, quality and endurance tests for gear boxes and drivelines • Development of drivelines for vehicles with one or more driven axles • NVH measuring LOAD UNIT FOR POWERTRAIN TEST CELLS AVL DynoWheel BENEFITS AT A GLANCE • Permanent magnet-excited synchronous motors with very low inertia adapted to the real vehicle wheel • Optimized for reproduction of realistic wheel loads and torsional behaviour • Accurate test execution and excellent repeatability due to high torque control linearity • The tire stiffness and slip is controlled by the AVL control systems with its digital real-time interface Two different characteristics are provided by this dynamometer: low mass inertia and very high torque at low speed. The inertia of the dynamometer is equal to the mass inertia of a vehicle wheel. Together with the wheel slip simulation, the same driveability as on the road can be simulated. Not only the vehicle acceleration but also the driveline vibration of the vehicle is similar to reality. Fast control loops make it possible to optimize the driveline for one or two driven axles. AVL DynoWheel drives are specially developed to provide the best results when highest accuracy and control dynamics are required.
