摘要：
An operating method for a roller-type test stand for a rail vehicle wheel set, in particular for simulating a sinusoidal run, has two parallel rail rollers, and the wheel set has two wheels which are connected to a wheel axle. The ends of the wheel axle are rotatably mounted in a first axle bearing and a second axle bearing. The wheels are in contact with the rail rollers in a respective base position of the axle bearings at a respective specified point of the rail rollers, and a first longitudinal actuator and a second longitudinal actuator each act on the first axle bearing or the second axle bearing in a longitudinal direction running transversely to the wheel axle.
