1. An operating method for a roller-type test stand for a wheel set for a rail vehicle, for simulating a sine run, wherein the roller-type test stand has two rail rollers which are arranged in parallel, the wheel set has two wheels which are connected to a wheel axle, wherein the wheel axle is rotatably mounted by its ends in a first axle bearing and a second axle bearing, in a respective base position of the axle bearings the wheels are respectively in contact with the rail rollers at a predefined point thereof, and a first longitudinal actuator and a second longitudinal actuator each act in a longitudinal direction, running transversely with respect to the wheel axle, on the first axle bearing or the second axle bearing, wherein, the first longitudinal actuator which acts on the first axle bearing is operated under force control, a deflection of the first axle bearing in the longitudinal direction with respect to its base position is determined, and the second longitudinal actuator which acts on the second axle bearing is operated under travel control, in such a way that a deflection of the second axle bearing is set with respect to its base position, which deflection corresponds in absolute terms to the deflection of the first axle bearing and is opposed to the deflection of the first axle bearing in the longitudinal direction. |
