Abstract

A test bench for carrying out aerodynamic measurements on vehicles is equipped with at least one contact surface for detecting the vehicle weight, a running belt for simulating the roadway moving under the vehicle, and at least one measuring device for determining forces acting upon the vehicle. According to the invention, the moving belt for simulating the roadway also forms the at least one contact surface for detecting the vehicle weight, and the running belt is in its entirety supported by a weighing plate, which is disposed via a bearing device relative to a stationary environment. At least one measuring device determines the forces acting upon the vehicle as a function of the movement of the weighing plate relative to the stationary environment.
