Experimental vibro-acoustic analysis of gearbox behavior using piezoelectric stack actuator excitation.
7th European Conference on Structural Control. Warsaw, Poland (July 2022)
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
In this paper, a new test-rig is designed to study the vibro-acoustic behavior of a simplified automotive transmission system. The aim is to experimentally reproduce the gear whine phenomenon in the gearbox, which is caused due to the transmission error without the need of rotating elements. Instead, an innovative method of excitation is proposed using a piezoelectric actuator. The test rig is designed to be an economical solution to otherwise complicated setups. Experimental investigations of the gearbox housing accelerations and noise emission are done, and the setup successfully captures the accelerations with its associated harmonics, with values that are very close to the state of a real rotating gearbox. In addition, a correlation is found between the housing accelerations and the emitted noise in certain frequency ranges. This setup will be used in future to test and integrate an active vibration control solution, to mitigate the generated vibrations and noise.
