Mechanical vibration is the study of oscillatory motion in physical systems, where a body or structure moves back and forth around a reference equilibrium point. This field analyzes the time-dependent motion of machines and structures, focusing on parameters like displacement, velocity, acceleration, frequency, and amplitude. 1. Fundamental Concepts

Methods to reduce undesirable vibrations, including vibration isolation (using isolators) and structural damping.

Swaying motion of a structure around an equilibrium position. Core Parameters:

A dangerous condition occurring when the external forcing frequency matches the system's natural frequency, leading to high-amplitude, damaging vibrations. 2. Types of Vibration
