Description

Analysis and modelling of two degree-of-freedom vibrating systems. Matrix representations of multi-dof systems. Free and Forced response calculation. Vibration of continuous systems - calculation of modal frequencies and shapes dependent on boundary conditions and wave equation. Forced vibration of continuous systems. Introduction to computer based simulation of mechanical engineering systems and use of commercial & development packages for simulation. 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
4. Formulate a State variable model of mechanical and other systems
5. Build dynamic models in Xcos and apply parameters through Scilab. Analyse and present output results.
