    摘要: A test stand arrangement comprises an electric machine (4) for driving and/or loading a test object (1) which is connected by means of a connecting shaft (2) having an adapter flange (3) to the electric machine (4).To be able to establish the connection of the drivetrain and vehicle simulation with the real vehicle-specific combustion and transient behavior of the engine, the arrangement consisting of connecting shaft (2) and drive and load machine (4) has a constant, predetermined moment of inertia, and the mass and the moment of inertia of the adapter flange (3) are selected in such a manner that the resonant frequency of the system consisting of test object (1), adapter flange (3), connecting flange (2), and electric machine (4) for driving and/or loading the test object (1) lies between the idle frequency and the partial load frequency of the test object (1).
