Definitions
- Wheelset wheelset To test the strength of wheelset axles in test benches, circulating bending loads are typically introduced into the shaft to be tested.
- the wheelset shaft to be tested is fastened on one side to the foundation with the wheel disc.
- the force is introduced by means of an unbalance exciter, which is mounted at the free end of the shaft.
- the bending stress applied in the shaft corresponds to the actual stresses during operation only at one point of the shaft.
- 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 approximately 20 Hz.
- 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 stand with the following features:
- the natural frequency and thus the test frequency increases, depending on Mass ratios to approximately 80 Hz. Due to the bending moment introduction via the two wheel disks, an almost constant circumferential bending moment arises between the two wheel disks, as is present during operation. In the area of the wheel discs, 2 vibration nodes are set during operation. In this node, the candidate can be hung.
- test rigs for checking crankshafts use 4 ropes or rods.
- brackets and the ropes themselves have a natural frequency below the desired test frequency.
- test time and the test costs can be significantly reduced.
- the necessary measuring technology can be easily mounted on the shaft. This standard measurement technology is used
- FIG. 1 shows a test stand according to the invention with a wheelset shaft to be tested and 2 shows an exemplary sectional view of a test stand according to FIG. 1.
- the test stand shown in the figures comprises two holding consoles 1 with rubber bearings 2 in which the wheelset shaft 3 to be tested with two wheel disks 4 is mounted.
- the wheelset shaft 3 is in the expected range of the nodes on the consoles.
