This page provides engineering information on vibrations and noise in mechanical systems, including free vibration, forced vibration, natural frequencies and response analysis.
The information supports engineers in analysing dynamic behaviour, identifying resonance conditions and designing systems to minimise vibration and noise effects.
Vibration analysis is an essential part of mechanical engineering design, particularly in rotating machinery, structures and dynamic systems where oscillatory motion can affect performance and reliability.
Vibration is the oscillatory motion of a body about an equilibrium position and is a fundamental aspect of mechanical systems. Vibrations can occur due to unbalanced forces, external excitations or system dynamics.
Understanding vibration behaviour is essential in engineering design to prevent excessive motion, reduce noise and avoid structural damage or fatigue.
Vibration analysis is widely used in rotating machinery, structural systems, automotive engineering and condition monitoring. It helps identify faults, optimise design and improve system reliability.
