A DISC BRAKE DESIGN AND ANALYSIS BY USING FUNCTIONAL GRADED MATERIALS

Abstract

The braking device is a vital part of the automobile industry. It is used to maintain vehicle speed and control. Therefore, it is necessary to find appropriate materials which can withstand heat generation and sustain the alternating mechanical load.

Functionally graded materials (FGM) are used as a fourth interface to improve layered composites' bonding strength, reduce residual and thermal stresses in different crosslinked materials, and as anti-corrosion coatings on engine and system components. Therefore, they have aroused great interest in recent years. One advantage of FGM over wafers is that there is no stress build-up at sharp material boundaries due to the continuous release of fabric elements to remove the structural integrity of the construction, including disassembly.

The results of numerical calculations are given for a specific frictional moment, made of functionally graded materials with titanium (disc) and aluminium (pad) alloys coated with graded ceramics closest to the friction surfaces.

Modeling is done in CREO and analysis is done in ANSYS.
