Abstract EN
Brake squeal phenomenon is a problem that has been long studied using multiple methods and theories.
Finite Element Method (FEM) has been applied to the study of brake squeal problem.
First, a disc brake model has been established.
Complex mode theory has been applied to the mode analysis and unstable vibration modes can be extracted subsequently.
The form of unstable vibration mode has been studied.
Then, transient dynamic simulation using explicit dynamic method has been performed.
Response in both time and frequency domain has been analyzed.
Two methods have been compared, considering accuracy and calculation consumption.
Then, the effect of different parameters such as coefficient of friction, stiffness, and brake force fluctuation frequency on squeal phenomenon has been analyzed.
It can be found that coefficient of friction and the brake stiffness have a positive correlation with the extent of brake squeal phenomenon, while the frequency of brake force fluctuation should remain as low as possible.
Afterwards, a ring-shaped layer of viscoelastic damping material is constrained to outer margin of the stator to restrain the unstable modal.
This method can change the vibration nature and improve the brake squeal problem.
