Summary:

In spite of many squeal noise studies, it is still hard to predict squeal noise these days. Squeal analysis is a useful technique in reducing or removing squeal noise. As a result, several papers that contain reasonable finite element model with correlation, squeal mode analysis, and design proposals that can reduce the squeal noise have been released.In this paper, Generalized Frictional Stiffness Matrix was extracted using Generalized Coordinate in ABAQUS. GFSM(Generalized Frictional Stiffness Matrix) is an unsymmetrical matrix which creates a real-eigen-value (unstable mode) in complex eigenvalue problem. Then, sensitivity of each term in GFSM is calculated. The least modification was proposed from the sensitivities to reduce the squeal noise. To verify this proposal, a reasonable finite element model was generated by correlating component and assembly modal tests. In processing correlation with component modal test, MAC(Modal Assurance Criteria) was used as a reference value for mode shape correlation
