This module is intended for graduate students and engineers interested in basic mechanical components used in wide range of mechanical systems. It covers the energy transmission and conversion systems both in the fluidic and mechanical domains. The concept of system dynamic modeling is introduced. At the end of the course, students are expected to know the standard mechanical components and systems well enough for designing mechatronic systems. Major topics of the modules are: Standard Mechanical Components, Mechanical Drive Components, Four-Bar Mechanisms, Classical Mechanisms, Thermal and Fluid System Elements, Pneumatic and Hydraulic Actuation Systems and System Dynamic Modeling.
