Advanced Engineering Dynamics

• Apply Newton’s second law and free body diagram to formulate equations of motion in rectangular- and polar coordinates for complex mechanical system.
• Apply Lagranges equations with generalized forces/torques to formulate equations of motion for complex mechanical system.
• Analyze equations of motion using both analytical methods and computer simulations.
• Apply analytical methods and computer simulations to solve equations of motion for mechanical systems.
• Apply analytical mechanics to solve practical engineering problems within machines, vehicles, robots and satellites.
• Apply computer software for graphic illustration of solution of equations of motion.
• Document technical calculations in reports with correct description of theoretical and experimental procedures, in a clear way, using technical terms, giving physical interpretations and evaluations of results.
• Acquire new knowledge in analyical mechanics.
• Understand and explain limitations of linearization of equations of motion.
• Read engineering and mathematical literature on advanced dynamics.
• Work in groups and cooperate on reports.

62694, A first course in engineering dynamics. Good mathematical background.

The teaching is based on ‘learning by doing’. There will be lectures, exercises and two projects with computer simulations. The projects will be done in groups from 1-4 students.
