Vibration

Definition

A periodic motion which repeats itself after a definite interval of time.

Purpose

Understanding vibration is crucial in various fields, from structural engineering to mechanical systems, as it affects the stability, performance, and longevity of structures and machinery.

Examples of Use

1. Analyzing building vibrations to ensure structural safety during earthquakes.
2. Monitoring machinery vibrations to detect and prevent mechanical failures.
3. Designing automotive suspension systems to minimize road vibrations.

Related Terms

• Oscillation: Movement back and forth at a regular speed.
• Frequency: The number of vibrations per unit of time.
• Amplitude: The maximum extent of a vibration measured from the position of equilibrium.

Notes

Excessive vibrations can lead to fatigue and failure in materials and structures, making vibration analysis a key aspect of engineering.
