Abstract Automotive dry clutches have been found to produce a low frequency sliding noise in many applications, which challenges the ride comfort of vehicles. In order to study this clutch sliding noise, a detailed finite element model including both a pressure plate assembly and a driven plate assembly was developed. Based on this model, a complex eigenvalue analysis is performed in this research. The effect of several major factors on the clutch sliding noise, such as the coefficient of friction, the clamping force, the geometric imperfection of the friction plate, and the thermal deformation of the… More >

Abstract The purpose of the present work is to study the disc brake squeal problem for passenger cars in order to reduce the instable high frequency squeal modes. The ABAQUS/Standard implicit method was used to perform dynamic contact vibration analysis of the current disc brake finite element model. The disc brake system studied here contains the caliper, bracket, brake disc, and brake pad. Notice that brake pad in general contains both brake lining and brake shoe. The brake pad with a specific chamfer pattern and the brake disc with a series of cooling ribs for ventilation… More >
