NUMERICAL SIMULATION FOR MECHANICAL BEHAVIOR OF THE DISC/PAD BRAKING TORQUE

A braking system is very important to a vehicle. It absorbs energy from moving parts, slows the vehicle through friction, and converts the vehicle's kinetic energy into heat energy that is released into the atmosphere. Disc brakes create an opposing torque on the wheel shaft, converting the wheel's kinetic energy into heat. During braking and when the rotating disc is in contact with the brake pad, which constitutes a friction body on the disc, the contact zone is subject to mechanical stress due to fatigue. The heat resulting from friction generated at the interface between the rotor and brake pads can exceed critical values, leading to very strong heating of the latter, causing undesirable effects such as deterioration phenomena, thermal cracking and thermoplastic instability. There is a possibility. In this study, a numerical simulation for the mechanical behavior of disc/pad has been used braking torque. This behavior was analyzed using the ANSYS computational code based on the finite element method for von Mises equivalent stress. It depends on the geometric parameters and mechanical properties of the disc and brake pad at the braking time t = 4.5 s. The purpose of this work is to identify the damages, improve the braking system, extend the life of this system and make it more reliable, the best choice and more resistant to damage to economical brake discs and pads.

Keywords: Disc Brake, Brake Pads, Mechanical Behavior, Ansys, Von-Mises Equivalent Stress.
