Dynamics of Mechanical Systems
Objectives
The objective of this course is to convey the fundamental concepts of dynamics of multiple body systems, thus allowing the development and analysis of mechanical systems used in different industrial applications. from mechanisms in general to biomechanics, robotics and vehicles.
The aim is thus to instruct students about the potentialities and limitations of numerical models constructed from the programming of equations of motion with Cartesian or other formulations, either by the use of commercial codes, promoting their rational and appropriate use with regard to representation of real systems and their components.
