The disclosed embodiments include a test stand (100) for the simulation of forces and moments introduced into a motor vehicle or into parts of a motor vehicle during driving operation. In order to allow a simulation of road journeys which is as realistic as possible, it being possible at the same time to dispense with vehicle-specific excitation or activation signals, there is provision, according to the invention, whereby the test stand (100) has at least one wheel contact plate (2) for receiving a vehicle wheel (1) and at least one first actuator (3a, 3b) connected at one side to the foundation (101) of the test stand (100) and at the other side to the wheel contact plate (2), for moving the wheel contact plate (2) along a first axis (L1), preferably along the vertical axis, relative to the foundation (101) of the test stand (100).
