A test bed and method for performing aerodynamic measurements on an object, in particular, a vehicle, are provided, in which a weighing plate serves to support the weight of the object. The weighing plate is mounted on a bearing device relative to a stationary environment. The bearing device is formed with at least one magnetic bearing.

Test bed and method for aerodynamic measurements on an object

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.
