Goals:
The development of insight in the two- and three-dimensional dynamics of rigid and structurally flexible bodies. Mathematical modelling of elementary mechanical systems and analysis of the dynamic characteristics of the mathematical model. Determination of mechanical loads occurring during the motion.
Computer use:
PC with MATLAB software
Laboratory project(s):
Part 2: computer execises during one afternoon. Part 3: computer execises during one afternoon.
Design content:
Throughout the course, system excitation and resulting system response is analysed, and avenues towards redesign of the system for improved performance are discussed.
