Brake squeal noise reduction in city buses 2019-01-1572
Buses have become one of the most widely used mode of public transportation, particularly for city applications. Indeed, passenger comfort and vehicle noise are a major concern faced by automotive industry. Brake system is one such contributor to undesired vibrations and obnoxious noise. Squeal noise, caused due to friction-induced vibrations, is a serious customer irritant to the bus passengers as well as the environment, also leading to brake performance deterioration and monetary abominations in terms of warranty costs.
Brake squeal noise has been considerably studied for over years. Several design modifications and structural changes have been incorporated to prevent the occurrence of squeal noise, but the issue persists.
In this paper, we have discussed on brake squeal noise reduction in city buses by optimisation brake drum diameter, selection of different friction liner linings and optimising other brake components sizes.
