The thesis by researcher Muhammad Ali Hassan, titled “Developing numerical and practical models for newly treated frictional materials for the brake system,” was discussed in the Department of Mechanical Engineering at the College of Engineering, University of Kerbala.
In order to predict how heat and stresses would be distributed throughout the brake system of SAIPA (compact small car), the thesis examined the thermal and mechanical behavior of the brake system. A mathematical model was constructed using the COMSOL Multi Physics V6 tool, and simulations of the single and multiple brake processes were carried out where the thermal characteristics of the rotating disc and brakes alter with temperature. On the experimental side, a lab device was created to represent the braking process in order to predict the effectiveness of the braking system. It uses three types of friction materials—FM1, FM2, and FM3 for brakes—as well as three types of friction materials—M479, MIM1, and MOO46 for rotating discs, all of which are affected by an initial speed that ranges from 80 to 140 km/h.
The maximum temperature as well as the maximum value of thermal and mechanical stress was anticipated by theoretical research of the thermal and mechanical behaviour.
In reality, under the influence of the given speeds, the maximum temperature and particular braking time predictions were reached.
The thesis was approved by the discussion committee, which was chaired by Professor Dr. Imad Qasim Hussein, and included Asst. Professor Dr. Jabbar Hussein Muhammad, lecturer Dr. Ahmed Qasim Hassan, Professor Dr. Uday Ibrahim Abdullah, and Asst. Professor Dr. Muslim Mohsen Ali.
