摘要

At present, for the relatively simple working principle, and low cost in the process, drum brakes are widely applied to automobile production. However, in the case of long-term use, its poorer heat dissipation, leads to corresponding problems, such as frictional squeal. Due to many squeal factors, this problem is difficult to break through. This study mainly performs corresponding analysis on complex modal analysis model for frictional squeal of an automotive drum brake and its affect factors. It performs corresponding verification analysis according to relevant principles and corresponding modal experiments, and analyzes the influence of brake pressure, friction coefficient and elastic modulus on corresponding frictional squeal[1]. It performs analysis through the experiment, to explore the corresponding influencing mechanism on the squeal.
