Abstract

THIS PAPER IS CONCERNED WITH THE DISC BRAKE SQUEAL PROBLEM FOR PASSENGER CARS. THE OBJECTIVE OF THE PRESENT RESEARCH IS DEVELOPING A FINITE ELEMENT MODEL OF THE DISC BRAKE ASSEMBLY IN ORDER TO IMPROVE UNDERSTANDING OF THE INFLUENCE OF YOUNGÂS MODULUS ON SQUEAL GENERATION. A DETAILED FINITE ELEMENT MODEL OF THE WHOLE DISC BRAKE ASSEMBLY THAT INTEGRATES THE WHEEL HUB AND STEERING KNUCKLE IS DEVELOPED AND VALIDATED USING EXPERIMENTAL MODAL ANALYSIS. STABILITY ANALYSIS OF THE DISC BRAKE ASSEMBLY IS ACCOMPLISHED TO FIND UNSTABLE FREQUENCIES. A PARAMETRIC STUDY IS CARRIED TO LOOK INTO THE EFFECT OF CHANGING YOUNGÂS MODULUS OF EACH BRAKE COMPONENTS ON SQUEAL GENERATION. THE RESULTS OF SIMULATION INDICATED THAT YOUNGÂS MODULUS OF DISC BRAKE COMPONENTS PLAY A SUBSTANTIAL ROLE IN GENERATING THE SQUEAL NOISE.
