/ 107 AVL DynoPrime The AVL DynoPrime series is designed to replace a combustion engine on gearbox and powertrain test stands. REQUIREMENTS The mass inertia of the dynamometer has to be equal to the inertia of the combustion engine. Torque pulses of a combustion engine must be simulated. The center height must be very low. If the dyno is mounted to the bell housing of a front wheel drive vehicle, enough space must be provided to mount the axle shafts. CHARACTERISTICS • Very low inertia • Low center height • High overload capability With its interfaces and dynamics, the AVL drive converter of the AVL DynoPrime corresponds to the converters of AVL DynoTrain and BENEFITS AT A GLANCE • Inertia similar to a combustion engine • High nominal torque (larger than ICE), plus additional overload torque capability for simulation of speed oscillations �� High ��e��i��ility in the parameterization of various characteristics of engines • Cost savings due to simpler setup of transmission and driveline testbeds �� Simple retrofitting into existing test cells is ensured by using the throttle as a demand value. Existing drive cycles can be used without modification AVL DynoWheel dynamometers. The real vehicle behavior can be simulated in a system with one AVL DynoPrime and two or four AVL DynoWheels. The dynamometers are water jacket-cooled and supplemented by a closed air-cooling loop for the rotor. This makes noise measurements on a gearbox test stand more efficient. APPLICATION • Development and optimization of the driveline before the vehicle engine is available • R&D for gearboxes, drivelines and vehicle parts that are in��uenced ��y the characteristics of the combustion engine • Wear tests under dynamic conditions • Noise measuring LOAD UNIT FOR DRIVETRAIN TEST CELLS AVL DynoPrime is a highly dynamic PMM drive system for the simulation of the rotational behavior of the crankshaft of combustion engines. The system is characterized by high nominal torques and a high overload capacity with the smallest moment of inertia.
