Braking system represents one of the most fundamental and critical safety components in modernrnvehicles. Brake absorbs kinetic energy of the rotating parts (Wheels) and the energy dissipated inrnthe form of heat energy to the surrounding atmosphere. It decelerates or stops the vehicle. Thernthesis describes the finite element analysis techniques to predict the failure region on the prernmaturity faller on disc brake to identify the critical locations of the components. The disc brakernimplemented on the front axle model with gray cast iron materials were studied in Disc brakernwhich commonly used in auto motives. Despite all the stresses experience by the disc doesnâ€™trndamage the disc due to high tensile strength but the disc may fail under fatigue loading. There isrnfrictional heat generated over disc surfaces, which leads to high temperature. Due to number ofrnbrake actuation, stress and deformations have generated on the disc surface. Hence, it reduce thernoverall performance and efficiency of the brake system. The problem in Volvo B11R Bus ofrnODAA integrated plc, which is imported in May, 2019 is that their disc brake is involving prematurernfailure.rni.ernbeforernservicernlifernofrn500,000rnkm.rnThisrnwillrninitiaternaccidentrnandrnleadsrntornlossrntornrnthernsupplierrnduerntorncomplainrnfromrntherncustomer.rnThernobjectivernofrnthisrnpaperrnwasrntornrnmodel andrnsteady state thermal and static structural analysis using finite element method (FEM). The methodrnused to this research is to obtain necessarily data to study parametric values are retention time,rnforce and torque. In order to make compare between actual prematurity failure and ANSYS resultrnvalues decreasing torque and force while keeping retention time and mesh size at constant resultrnin decreasing in both total deformation and Von miss stress. The maximum total deformation isrn2.2424e-005m, the Von miss stress is 1.067e+008 Pa compressive ultimate strength 8.2e+008 pa,rntensile ultimate strength 2.4e+008, compressive yield strength 1.e+009, tensile yield strengthrn1.e+008 and temperature result 420 â„ƒ . The ANSYS result shows that the crack that is happeningrnin the busâ€™s disc break is due to the increase in toque, force and temperature which result in higherrndeformation and stress. Thus we obtained the values of total deformation, Von-miss stress andrnthermal effects on disc brake, and interpreted them to explain the cause of the failure.
