Abstract

One of the important parts of the passenger vehicle is its braking system or specifically the brake pedal. This has been taken as the main research subject of this Final Year Projek (PSM). The measurement of stress and strain conditions of the brake pedal was determined by conducting a compression test to the brake pedal by controlling the travel distance of brake pedal. The study was done by designing and fabricating a special test fixture to hold the brake pedal while conducting the compression test by applying to static loading through the Instron universal testing machine. The compression load was applied to the brake pedal at three different areas and with three different travelling distance of 2 mm, 3mm and 4 mm respectively. And the areas of applying force is at the centre, left and right side of the brake pedal and is known as F1, F2 and F3 locations respectively. The strain gauges are installed at the critical part of the brake pedal and connected to the strain meter for the determination of strain readings at the specified locations. The load of every position of applying force and travelling distance of braking system has been recorded together with the strain gauge readings. Based on this study, the main achievement of determining the value of maximum stresses or strains at the critical locations of the brake pedal has been done though some influential factors have significantly affected the final results. Other than that, the determination of maximum load that the brake pedal can withstand at three different areas of applied force and three different travelling distance of brake pedal has also been carried out successfully.
