Vibration analysis and control are increasingly important as technology races forward. Vibrations are caused by many phenomena, such as fluid flow and combustion. The study of vibrations touches a multitude of disciplines. In fact, vibration analysis is important to physicists and mathematicians, as well as to engineers. As such, vibration analysis has evolved into a very sophisticated and elegant field where the most current tools for analysis are available, such as chaos and fractal theory.
There are four labs are available in this topic:
Free and Forced Vibrations
- Investigating the effect of added mass on the natural frequency of the Simply Supported Beam.
- Studying the relationship between oscillation amplitude, phase lag, magnification factor and speed ratio.
- Understanding the damping effect on the oscillations in a simply supported beam assembly.
- To show how an auxiliary oscillating system can help to absorb the vibrations of a simply supported beam.
- To show the three key frequencies of the two degrees of freedom (2DOF) system - and resonance at upper and lower system natural frequencies.
Vibrations of Continuous Systems
- To determine the first three transverse natural frequencies and mode shapes of a given continuous system using both experimental and theoretical techniques.
- To compare results with those from published results.
Driven Damped Harmonic Oscillations
- Studying the dynamics of a torsional pendulum and measure its first natural frequency.
- Investigating the effects of damping on the dynamics and natural frequency of the torsional pendulum
Driven Damped Harmonic Oscillations-3DoF
- Studying the dynamics damped of 3 degrees of freedom system and measure their natural frequencies and mode shapes.
- Investigating the effects of damping, mass and springs on the dynamics and natural frequency of the 3 degrees of freedom system.
