Simulation of mechanical systems and components including machine elements, electrical and electro-mechanical systems, thermal systems, and hydraulic systems. State-variable modelling and techniques for validation of models.

Learning Outcomes

1. Analyse 2 DoF vibrating systems for modal frequencies and shapes and response to harmonic excitation
2. Determine the wave equation for 2nd & 4th order systems and apply boundary conditions to define mode shapes. Perform modal and forced-vibration analyses of simple continuous systems.
3. Develop modelling strategies for multiple DoF simulation
