    Abstract
  • In order to study the generation mechanism of railway disc brake squeal and its influencing factors, the disc brake squeal of a railway brake unit for several different brake conditions in a field test was measured, and the generation mechanism of railway disc brake squeal was obtained. Based on the mechanism of brake friction squeal caused by modal coupling, a full-size prediction model of brake squeal was established, which included a disc, two brake pads, two pad holders, two levers, and several pins. The friction coefficients between the pads and disc from a laboratory test were used in the prediction of brake squeal. The factors affecting brake squeal were studied in the model. The test results show that the characteristic frequencies of disc brake friction squeal are 256.78, 3904.07 Hz and 4320.38 Hz, respectively. When the thrust force is equal to 10.1 kN and 12.3 kN, disc brakes are most likely to produce friction squeal in brake applications, the predicted results of the model are in agreement with the measured frictional squeal. The elastic modulus of the brake pad has an important influence on disc brake squeal, the reasonable elastic modulus of brake pad is helpful to suppress the brake friction squeal.
