Study on Brake Squeal by Feed-In Energy Analysis 2001-01-0950

Brake squeal noise is studied in this paper by feed-in energy analysis. Based on the closed-loop coupling brake model, the computation method of feed-in energy is derived for the system squeal mode. The amount of feed-in energy can indicate the degree of squeal tendency of the brake system. Feed-in energy analysis can clearly reveal the influence of some structural parameters on brake noise, such as coefficient of friction, the geometric shape and stiffness of pads, and key substructure modal shape. It also can help to analyze the structure modification to eliminate brake squeal.
