The modeling of thermal and mechanical effects during braking has become increasinglyrnimportant in product design in different transport means, road vehicles, airplanes, railwayrnvehicles, and so forth. The thermal and mechanical analysis is a very important stage in thernstudy of braking systems, especially of railway vehicles where it is necessary to brake hugernmasses because the thermal load of a braked railway disc prevails compared to other types ofrnloads. In the braking phase, kinetic energy transforms into thermal energy resulting in intensernheating and high temperature states of railway discs. Thus induced thermal loads determinernthermo-mechanical behavior of the structure of railway discs. In cases of thermal overloads,rnwhich mainly occur as a result of long term braking on down grade railroads and braking tornstandstill on a flat railroad, the generation of stresses and deformations occurs whosernconsequences are the appearance of cracks on the discs, brake judder, thermo-elasticrninstability and finally brake disc failure. The importance to precisely determine therntemperature distribution caused by the transfer process of the heat generated during brakingrndue to the friction on contact surfaces of the braking system makes it a challenging researchrntask.rnTherefore, analytical and numerical modeling of thermal and mechanical analysis during longrnterm braking for maintaining a constant speed and braking to standstill afterwards on a downrngrade railroad and braking to a standstill on a flat track is processed in detail in this research.rnEven though brake disc is commonly made from cast iron, an attempt has been made torninvestigate the suitable composite material which is lighter than cast iron and has goodrnyoungâ€™s modulus, yield strength and density properties. Aluminum base metal matrixrncomposite has a promising friction and wear behavior when used as a disc brake. Brake discrnmade from SiC/6061Al alloy composite material is used and an investigation is made onrnthermal and mechanical loads analysis for Addis Ababa LRT EW route brake applications.rnConsequently the result revealed that SiC/6061Al alloy composite material can effectivelyrnenhance the thermal and mechanical performance of the brake disc.
