Snižování hluku kluzného uložení diferenciálu

Noise Reduction of the Differential Sleeve Bearing

en

This article describes a technique for noise reduction of the differential bearings. Noise is excited by the mechanical looseness of the system and by the vibrations of the engine. The mathematical model enables the optimization of the radial stiffness of the differential bearings. A test rig has been designed for the simulation of the phenomenon outside the vehicle. Analytical software has been created that is capable of classifying the types of noise from the measured data. The optimal solution is tested on the rig at the end, thus proving that the technique works.

Článek popisuje metodiku minimalizace hlukového projevu ložisek diferenciálu. Hluk je způsoben mechanickou uvolněností systému a vibracemi hnacího agregátu. Matematický model umožňuje optimalizovat radiální tuhost ložisek diferenciálu. Je navržen zkušební stav pro simulaci jevu mimo automobil. Navržený měřící a analytický program klasifikuje typy hlukového projevu. Na závěr je optimální varianta testována na zkušební stanici a je potvrzena funkčnost metodiky.
