Abstract
Reducing disk brake squeal, especially low frequency disk brake squeal (1-5kHz), is an important technical issue in vehicles. The disk brake squeal mechanism has been shown in many papers (1), (2), (3), (4), (5), (6), (7), (8) and (9). Recently, the disk brake squeal comes to be simulated by Finite Element Analysis (FEA) for disk brake design (10), (11), (12), (13), (14), (15), (16), (17), (18) and (19). Though FEA is useful, it is sometimes difficult to modify in large when the prototype of disk brake system has been designed. First Order Analysis gives design concepts, which should be done before FEA. This paper shows First Order Analysis of low frequency disk brake squeal. The equation of motion is shown in 4 degrees of freedom model. In this equation the generalized force matrix is composed of the variations of pressure and friction force between each brake pad and brake disk. The generalized force matrix is arranged with a symmetric matrix and an anti-symmetric matrix. Anti-symmetric matrix sometimes causes the dynamic instability, which represents disk brake squeal generation. This paper shows the stabilization of the system with making it symmetric, and gives the design concept for reducing low frequency disk brake squeal.
