Comparative tests of several versions of a damped gearwheel were carried out for the MIBA Group at our test institute. The focus was on the vibration and temperature behavior under realistic conditions.

The test environment included:

  • Two test series: one at room temperature and one at 100 °C

  • Vibration exposure in the frequency range of 50–800 Hz with accelerations up to 10 g

The test part change at 100 °C posed a particular challenge. All 12 test parts were preheated, mounted on the test jig at a constant temperature and fitted with measuring equipment. The natural frequency behavior of the gears was analyzed in both thermal states.

Result: In addition to precise data on temperature behavior, continuous high-temperature control of the components led to a significant reduction in testing time.
