Squeal of a Disk Brake of Floating Type for Cars. 2nd Report. Analytical Results.

Abstract

This paper presents an analytical model coupled between rotor and caliper through pads to analyze the low frequency squeal of floating type disk brake, and describes the analytical results, compared with the experimental ones shown in the previous report. From the analysis, it was made clear that the squeal changes according to the contact distribution in the circumferential and the radial directions between rotor and pads, that is, in the case of cutting a part of pad surfaces in the circumferential direction, it is effective for squeal reduction to cut the pointed end pad surfaces of leading side on the inner side, and in the case of cutting a part of pad surfaces in the radial direction, it is effective for squeal reduction to cut outer pad surfaces of inside in the radial direction. It was confirmed that these analytical results were in a fine agreement with the experimental ones.
