Design and Analysis of Finned a Brake Drum by Using FEA – Truck: A Detailed Approach

Abstract

The present study highlights the design and analysis of Finned a Brake Drum by Using FEA – Truck, In automobiles, the braking system is essential. With the aid of the brake shoe interface, it operates according to the brake actuating mechanism principle. The braking system uses fiction to convert energy.  The custom-made brake drum made of different materials like are Greycast iron, EN AC-41700 Cast Aluminum, Grade 1600 Au tempered Ductile Iron; H950 (S45000) hardened stainless steel, Titanium 6-6-2(R56620) etc Between the thresholds temperature of inside the brake drum, stresses and deflections, heat flux are measured for the existing design and modified design, the brake drum. Modeling is developed in CATIA V5 R20 and analysis is done in using ANSYS Workbench 14.5. In  general  brake  discs  (single  or  multiple)  made  as  solid, vented, drilled, divided etc., are combined with the pads covering the rubbing path of the disc(s) partly or within the entire circumference  (aircrafts).  The  latter  is  used  to  increase  the  friction  force at the  same  contact  pressure.  The  pad  also  may  be  performed as single or multiple (e.g. mine hoist disc brake systems) friction areas  per  one  side  of  the  disc. In order to increase the life of the brake drum, the paper will concentrate on reducing design stresses, decreasing stopping distance and braking force, increasing braking efficiency, and reducing heat inside the brake drum.
