Abstract

Objective of this project is to design and develop car door lock actuator using shape memory alloy (SMA) material. Conventional car door lock actuator using motor to actuate the actuator. Several design of SMA actuator has drawn and one best design is choose to be develope as prototype. Design considerations state at the beginning of the project and the design must follow the parameters. Then, every design will be discuss to choose the best while mark will be given. The highest will be the best design. In this project, the shape memory alloy (SMA) is a group of materials which have the ability to return to a predetermined shape when heated. Due to this special behavior, the shape memory alloy has a wide variety of practical applications such as actuator due to its unique super-lasticity and shape memory effect. The design is drawn by using CATIA CAD Software begin with sketch in plain paper to determine it parameter. Conclusion of this project is the shape memory alloy (SMA) can be use as new car door lock actuator replace the conventional car door lock actuator using motor
