ROLLER-TYPE TEST STAND, AND OPERATING METHOD FOR A ROLLER-TYPE TEST STAND

摘要

The invention relates to an operating method for a roller-type test stand for a rail vehicle wheel set, in particular for simulating a sinusoidal run. The roller-type test stand 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. The method is characterized in that the first longitudinal actuator acting on the first axle bearing is operated in a force-regulating manner, and a deflection of the first axle bearing relative to the base position of the axle bearing is determined in the longitudinal direction. The second longitudinal actuator acting on the second axle bearing is operated in a path-regulating manner such that a deflection of the second axle bearing relative to the base position of the axle bearing is set, said deflection corresponding to the deflection of the first axle bearing in terms of magnitude and being opposite the deflection of the first axle bearing in the longitudinal direction. The invention further relates to a roller-type test stand which has a regulating device for carrying out the method.
