Measuring Vibration with Accelerometers

Jul 15, 2020Vibration is the movement or mechanical oscillation about an equilibrium position of a machine or component. It can be periodic, such as the motion of a pendulum, or random, such as the movement of a tire on a gravel road. Vibration can be expressed in metric units (m/s 2) or units of gravitational constant "g," where 1 g = 9.81 m/s 2. An
