摘要

The wheels on the axle under test rest on rollers or similar and are driven in opposite directions during testing. The rotation speeds of both wheels are measured during testing and are maintained equal by a controller controlled by the measurement result. The peripheral or angular spees of the wheels may be measured comapred and used for the control. For angular speed measurement the rotation time of wheel marker's measured. The wheel rotation angle may be used in conjunction with the peripheral speed measurement.
