Abstract

The design of braking system of a vehicles is very important in order to minimize the accidents and increase the life span of vehicle, with this motto, in this paper presented the structural analysis, fatigue analysis and thermal analysis of disc brake with slots (DBS) is done by considering various materials of DBS such as carbon alloy, steel and carbon steel. The comparison of those materials is studied in various mechanical and thermal properties such as deformation, strain, stress, factor of safety, number cycles under cyclic loading and heat flux. Simulation studies were done in Ansys 14.5 version. It is observed that the heat flow rate is high in carbon alloy and low in carbon steel material of DBS model. Maximum stress is observed in steel in structural analysis.

Braking system is one amongst the vital safety parts of a vehicle
Structural analysis, fatigue and thermal analysis are done in Ansys 14.5 Simulation tool but the modeling of plane disc rotor brake was modeled in Solid Works
It is observed that the maximum deformation in carbon alloy and minimum value in carbon steel under constant load

Summary

INTRODUCTION

Braking system is one amongst the vital safety parts of a vehicle. It’s primarily wont to decelerate vehicles from an initial speed to a given speed. As a result of high temperatures will result in heating of the brake fluid, seals and different parts, the stopping capability of a brake will increase with the speed at that heat is dissipated because of forced convection and thermal capability of the system [1].Brake disc convective cooling has been traditionally studied by suggests that of experimental and theoretical strategies [2, 3] and the improvement was solely boosted with the arrival of contemporary procedure resources within the late Eighties [4]. The friction heat generated between two slippery bodies causes thermoelastic deformation that alters the contact pressure distribution. This coupled thermo-mechanical method is referred to because the frictionally-excited thermoelastic instability [5]. The fatigue and thermal analysis of DBS model is presented with various materials such as carbon, steel and carbon steel
