    Description / Description Test bench for wheel set shafts 5 To test the strength of axles in test benches, circulating bending stresses are typically introduced into the shaft to be tested.
    The wheelset shaft to be tested is fastened on one side to the foundation with 10 of the wheel disc. The force is introduced by means of an unbalance exciter, which is mounted at the free end of the shaft.
    The applied bending load in the shaft ent-15 speaks only at one point of the shaft the actual stresses during operation. The bending stress decreases continuously from the clamping point to the free end with the unbalance exciter. Due to the design, the test frequencies are limited to about 2 GHz. 20
    The invention has for its object to better adapt the test to the actual loads during operation of the wheelset. This is done according to the invention with a test bench with the following features: - the wheelset wheels to be tested have two mounted wheel discs, - the bending moment is introduced via the two Radsehe L-30 ben, - the bearing of the wheelset to be tested on the holding brackets in the expected range of Vibration nodes by means of rubber bearings, - Grundigenfrequenzen the retaining brackets are above the test frequency.
    By testing the shafts with 2 mounted wheel discs increases the natural frequency and thus the test frequency, depending on 2/6 2 201302322
    Mass ratios to about 80 Hz. Due to the bending moment introduction via the two P.adscheiben results between the two wheel discs, as in operation, almost constant, circumferential bending moment. In the area of the wheel disks 5, 2 vibration nodes are set during operation. In this node, the candidate can be hung.
    Known test rigs for checking crankshafts use 4 ropes or rods. However, the necessary components, the 10 consoles and the ropes themselves have a natural frequency below the desired test frequency.
    When mounting the wheelset shaft in 2 special rubber bearings very compact retaining brackets can be used. 15 The basic natural frequencies of these holding consoles are above the test frequency. This avoids disruptive influences on the test procedure on the test bench. Due to the close-to-ground arrangement of the specimen, the handling and installation of the specimen is greatly facilitated. The measuring technique necessary for monitoring the test run is also substantially simplified (no rotating components and only slight vibration movements) 25 With the test stand according to the invention, test time and test costs can be considerably reduced.
    The necessary measuring technology can be easily mounted on the shaft. Standard metrology is used with this 30
    The invention will be explained in more detail with reference to an embodiment shown in FIGS. 35 Show it
    Fig. 1 shows a test stand according to the invention with a wheel axle to be tested and 3/3 3 201302322
    2 shows an exemplary sectional view of a test stand according to FIG. 1.
    The test stand shown in the figures comprises two retaining brackets 1 with rubber bearings 2 in which the wheelset shaft 3 to be tested with two wheel disks 4 is mounted.
    The bending moment introduction takes place by means of unbalance exciter 5 via the two wheel discs 4.
    In this case, the wheelset shaft 3 is in the expected range of the nodes on the consoles.
    Also important is an interpretation of the holding brackets in such a way that their Grundigenfrequenzen are above the test frequency and thus influences on the measurement result can be avoided.
