Özet:

 

Minimising noise is becoming an increasingly important factor in motor   vehicle development. The importance of this development goal is   increasing with rising customer expectations and increasingly stringent   legal restrictions on noise emissions. The cause of rattling and   clattering noise is torsional vibration of transmission components   that are not under load, that move backwards and forwards within their   functional clearances. This noise is perceived as distinct from other   sources of noise, and is intrusive because of its undesirable character.   The transmission parameters backlash, axial clearance and main centre   distance were varied by experimental analyses in test stand trials,   showing the effect on propensity to rattle and clatter. By optimising   these parameters, it was possible to minimise the rattling and   clattering noise. Measures internal to the transmission to reduce   loose part vibration in vehicle transmissions were also considered.   The calculated noise level with the EKM-Simulation program correlates   with the measured noise level. Parameter studies with the EKM-Simulation   program, which contains all relevant parameters for the excitation of   rattling noise caused by idle gears, shows the significant parameters   for the investigated transmissions.
