This research is about designing a new concept of a brake system using smart materials.
Smart materials are materials that receive, transmit or process a stimulus and respond by
producing a useful effect. Smart materials have attracted researchers' attention in
venturing a new technology that can improve our lives. There are a lot of materials that
have been considered as smart materials. In this research a new type of material which is
Ferromagnetic Shape Memory Alloy (FSMA) has been chosen. This alloy have
significant advantages in term of producing a large scale of output effect and delivering
fast response times compared to the other types of materials Based on these factors
FSMA can be an appropriate material as an actuator for brake mechanism systems.
After the invention of FSMA in early 1990s by Dr. Kari Ul\ako, lots of
research laboratories has set up new research groups in order to have a better
understanding about this material. Up to now they are still venturing the ways to develop
this material as actuators. There are a lot of potential field of application such as couplers
element, vibrators element, sensor and generator element, fluidic element and positioning
devices. FSMA products that have been made available in the market are linear motor
and fluidic pump from Adaptamat Ltd. FSMA has a big potential to replace current
mechanical actuator and machinery such as pneumatic and hydraulic.
In designing a brake system for robot applications there are several design
constraints that need special attention. The design must be light and compact so that it
will not become a significant additional load to the robot. In this robot application the
brake system has a slightly different requirement. The brake torque is required to provide
grips to the rotary shaft and not to stop the wheels. So in this application an initial
braking torque is preferred.
The research also gives special attention in finding an innovative way to
improve the methodology of designing and developing mechatronic products. A new
approach using the UML 2.0 has been used as a modelling technique. The technique is a
well proven technique in the software engineering applications and with a minimum
modification it is now suitable for the mechatronic engineering. Based on the results that
have been achieved in this research the integration of the UML 2.0 with the Pahl and
Beitz design methodology and the V-model has been successful.
