Actuators are significant elements to drive mechanical systems. Due to the multiple requirements and the development of advanced materials and processing technologies, the development and application of advanced actuators are required with high-performance and/or availability in extreme environments. In this course, piezoelectric, electrostatic, fluid power and shape memory alloy actuators with different working principles and soft and micro actuators with different functionalities are taken up and their working principles, performance, control methods and applications are explained. The fundamentals of advanced mechanical engineering are covered.
As key technologies in mechanical engineering, this course aims at building a fundamental of advanced mechanical engineering by offering technological information of various advanced actuators with different working principles and functionalities.
At the end of this course, students will be able to:
1) Describe working principles and performance of advanced actuators such as piezoelectric, electrostatic, fluid power, shape memory alloy, soft and micro actuators.
2) Describe control methods and applications of advanced actuators.
3) Design advanced mechanical systems with wide variety of specifications selecting adequate actuators.
