Design Modification of Brake Disc Materials on Thermal and Structural Analysis for Automobiles 2020-28-0392
During braking a large amount of kinetic energy being taken form into thermal energy thereby increasing the brake disc temperature around 200oC to 400oC in motorcycles and ATVs, which forces to improve the heat transfer in brake disc through grooves and holes thereby minimising the clamping force. In which the present study is mainly done to improve the clamping force on the brake disc through re-coined the shape of grooves with various disc materials by design and analysis route. The brake disc solid work model was developed with slanted rectangular grooves along the radial direction of Aluminium metal matrix composite (AA8081 reinforced with 15wt% of SiC and 3wt% of Gr), Stainless Steel (SUS 410), Gray Cast iron (Grade 250) materials data set. The couple field analysis attempts of both thermal and structural analysis was done to find the impact on the brake disc heat transfer rate, deformation, von mises stress and strength which were analysed by ANSYS workbench. To assure safe braking condition, towards increase in the area of contact between the brake pad and disc material of AA8081 reinforced with 15wt% of SiC and 3wt% of Gr shows better responses were observed than other grades. Due to the better heat transfer rate for both aspects of proposed grooves with high strength composites. This out reached design and material may suitable for automobiles in next level of alternatives in brake disc.
