The Optimum Design of Rotor Shape in Front Disk Brake System for Squeal Noise Reduction using the DOE
실험계획법을 이용한 전륜 디스크 브레이크 시스템의 로터형상 스퀼소음 저감 최적화
Abstract
This paper deals with friction-induced vibration of disc brake system under constact friction coefficient. A linear, finite element model to represent the floating caliper disc brake system is proposed. The complex eigenvalues are used to investigate the dynamic stability and in order to verify simulations which are based on the FEM model, The comparison of experimental and analytical results shows a good agreement and the analysis indicates that mode coupling due to friction force and geometric instability is responsible fur disc brake squeal. And the Front brake system reduced the squeal noise using design of experiment method(DOE). This helped to validate the FEM model and establish confidence in the simulation results. Also they may be useful during real disk brake model.
