Abstract
A test stand arrangement includes at least one electric motor (4) connected to a test specimen for driving and/or loading the test specimen, and a control arrangement for the or each electric motor. In order to be able to create the connection of the drive train and vehicle simulation with the real, vehicle-specific combustion and dynamic behavior of the engine, at least one model for a multi-mass flywheel is implemented in the control arrangement, from which model at least a part of the control requirement for the or each electric motor is calculated and which model contains at least the two masses of the primary and secondary side of the multi-mass flywheel and a substitute model for the or each bow spring, and an algorithm is implemented in the control arrangement that analyzes the model for a multi-mass flywheel by means of an integrated time step method.
