| Description:
| Aims:To introduce the vibrations of mechanical systems in a one degree of freedom context.
To introduce the theory of torsion in non-circular and open- sections, dual axis bending and the concept of fatigue failure. Learning Outcomes: After taking this unit the student should be able to: * Set up the equations of motion for systems with one degree of freedom; find natural frequencies of free motion; calculate rates of decay from viscous damping and vice versa; determine motions resulting from a sinusoidal force, unbalance and base excitation. * Estimate maximum responses using shock spectra. * Calculate shaft critical speeds. * Calculate torsional stiffness and strength values for closed and open structural sections. * Predict bending stresses in dual axis bending. * Predict the fatigue life of some simple structural forms based on S-N calculations. Skills: Problem solving; numeracy; working independently. Content: One degree of freedom systems: free and forced vibration; base excited motion; unbalance excitation; vibration isolation. Torsion of open and closed structural sections, dual axis bending. Stress concentration, fatigue strength and cumulative damage in structural components. Solid mechanics laboratory experiment. |
