Abstract

Shape Memory Alloy (SMA) is a special metal alloy that has a very unique character. Because of this unique property, SMA can be used in mechanical applications such as automotive. The unique property is its ability to remember its original shape after charging certain circumstances. The situation involving changes in temperature and because the SMA has two phases: martensite and austenite. In these two situations is the ability to produce. This special characteristic can adapt as the actuator. This project is about using SMA alloy to replace the conventional actuator for parking brake system, the parking brake pedal. By using SMA alloy, the parking brake pedal will be removed and being replace with SMA actuator. The SMA actuator needs to be design so that it can work as effective as the conventional parking brake system. Several experimental methods will be using to analyse the potential of the SMA actuator comparing the conventional parking brake. From the idea above, then emerge into the idea of applying the SMA actuator into automotive application and the study using SMA in a vehicle braking system has been carried out.
