Abstract

One of the physical problems that can be found in heat transfer is heat transfer to a vehicle brake. In this study a focused vehicle is a motorcycle. Where the heat transfer of the brake system on the motorcycle in this study was completed finite element method. The purpose of this study is to analyse one of the problems of displacement in the three dimensions of the motorcycle brake. So, the results obtained in the form of the best time in the braking for motorcycles. The settlement method is to use one of the partial differential equations for heat transfer. One of them is the Elemenisation model is the braking system. As is known braking system is a system used to slow and stop the vehicle. During the braking phase, the vehicle's kinetic energy will be converted into heat energy due to the friction action of the brake system. The heat flux produced by effects to the brake lining is ideally dissipated into the environment to avoid brake friction pad emissions. The heat produced has a tendency to evaporate the brake fluid and the disc brake surfaces will become hot. Based on the results obtained, when the braking system is in operation, the most significant heat transfer in t = 3.8s. This time is the best time to avoid excessive brake fluid evaporation and the rapid breakdown of the brake surface due to excessive heat.
