NUMERICAL STRUCTURE ANALYSIS OF REAR DISC BRAKE CALIPER BRACKET MINI DIRT BIKE 50cc

Abstract

The numerical structure of the rear disc brake caliper bracket on a 50cc mini dirt bike will be studied. This study includes modeling bracket design using the finite element method. The analysis is focused on the distribution of tensions, strains, and deformations resulting from static loads. The selection of the material used is aluminum alloy 6061-T6 and cast carbon steel is often used because of its light and strong nature. In addition, finite element analysis
(finite element method) helps in evaluating the strength, maximum voltage, as well as safety factors of the designed components. This research focuses on the optimal design of brake caliper brackets for applications on 50 cc mini dirt bikes. Two variations of design optimization were introduced through a weight optimization process to achieve a maximum mass reduction for 6061-T6 aluminum and Cost Carbon Steel of 10.38% and 10.8% of the initial weight, respectively. The results of the study with loading from 0 N to 300 N simultaneously showed the maximum value of Von Misses Stress for aluminum 6061-T6 and Cost Carbon Steel of 6.12x107 Pa and 8.34x107 Pa, respectively. Then the maximum strain values on aluminum 6061-T6 and Cost Carbon Steel are 0.020 mm and 0.00347 mm, respectively. Finally, the maximum safety factor values for 6061-T6 aluminum and Cost Carbon Steel are 3.55 and 8.04, respectively.
