Analysis of free and forced vibrations in single and multi-degree systems.
Course overview
This course examines the principles of mechanical vibrations, focusing on the dynamic behaviour of systems subjected to oscillating forces. You will model mechanical components as single and multi-degree-of-freedom systems, deriving equations of motion to predict their vibratory response. The curriculum covers free and forced vibrations, damping effects, and resonance phenomena.
Through theoretical problem-solving and laboratory work, you will learn to identify natural frequencies and calculate mode shapes. These skills are essential for designing systems that avoid destructive resonance, such as rotating machinery, structural components, and vehicle suspensions.
