Optimized Thermo –Structural Analysis of Solid and Vented Disc Brake Using Finite Element Mathod (A Case Study)

Abstract

The disc brake is a device for slowing or stopping the rotation of a wheel. Friction causes the disc and attached wheel to slow or stop. Brakes convert friction to heat, but if the brakes get too hot, they will cease to work because they cannot dissipate enough heat. Disc brakes are exposed to large thermal stresses during routine braking. The main cause of this paper is to minimize the thermal stresses with best suited material, best suited design & give optimized result. This paper studies about the model of a disc brake used in TATA SUMO N/M, 207 DI, 207EX - Wheeler; data has been given by R.M.ENGG, RAJKOT;GUJRAT. Analysis is also done by changing the design of disc brake. Actual disc brake has no holes; design is changed by giving holes in the disc brake for more heat dissipation. In this paper, the author has investigated on ventilated and solid disc brake rotor of normal passenger vehicle. The work considers heat and temperature distribution on disc brake rotor. Modeling is done in Pro/E (3D-Modelling-software) and Analysis is done in ANSYS (finite element analysis-software). Thermal and Structural analysis is done on the disc brake. The materials used are Stainless Steel & Gray cast Iron. Both results have been compared for better justification. Thus, both results provide better understanding on the thermal characteristic of disc brake rotor and assist the
