Design, Implementation and Testing of a Locking System

The paper aims to determine the characteristics of intelligent materials, in this case nitinol, but also to determine its behavior in different situations of the application made and tested. To determine the characteristics and behavior of nitinol, a device was made in the form of an actuator that performs a movement due to the forces that are born in this material, forces that are obtained from the change of temperature. The device is called a locking system that performs compression - decompression, respectively closing - opening movements of the actuator, being controlled by the electric current applied to the ends of the nitinol element and can be used in applications such as cars.
