摘要： A mobile test unit for testing a powertrain component such as a transmission is used in a test cell. A test unit includes a movable, generally horizontal base plate, and a frame spaced from the base plate. A headstock is secured to the frame for supporting the transmission. An adjustable support, which is arranged on each of four corners of the frame in the example embodiment, interconnects the frame to the base plate. The adjustable supports are movable in a vertical direction, in one example, between multiple positions to achieve a desired orientation relative to the base plate. In particular, the orientation of the frame is adjusted to obtain a desired rotational and/or tilt angle that corresponds to a rotational and/or tilt angle of the transmission when installed into a vehicle. The transmission can be installed onto the test unit, and the test unit can be moved into and out of a test cell. The example test unit is capable of replicating the orientation of the transmission when installed in a vehicle to provide more representative test data. Furthermore, the adjustments to the test unit can be done outside of a test cell to increase the time during which the test cell can be utilized.

摘要： Method of simulating the performance of a vehicle on a roadway on a power train test bed with the help of torque-controlled electric load machines mounted on the shafts of the power train of the vehicle and with the help of a computer with a vehicle model stored therein and a tire model simulating the slip-dependent friction, in which method the angular wheel speed is measured on at least one of the shafts, and the tire model determines a force transmitted from the tire to the roadway at this angular wheel speed on the basis of the tire model using a vehicle velocity and a tire normal force, and it also determines a setpoint torque for this force for the torque-controlled load machine mounted on this shaft, in such a way that a difference corresponding to the actual slip is established between the measured angular wheel speed and a nominal angular wheel speed value corresponding to the vehicle velocity used in the tire model and calculated in the vehicle model with feedback of the force transferred to the road surface.
