Measuring Vibration with Accelerometers

 · Vibration is most commonly measured using a ceramic piezoelectric sensor or accelerometer. An accelerometer is a sensor that measures the dynamic acceleration of a physical device as a voltage. Accelerometers are fullcontact transducers typically mounted directly on highfrequency elements, such as rollingelement bearings, gearboxes, or spinning blades.

rolls). Without measuring the vibration in all three directions, you don't know the exact contribution of the rotating rolls to paper machine vibration. This is why a complete vibration study must be performed. Vibration analysis may be undertaken as a standalone process, or may be part of a machine section audit or comprehensive machine analysis.

Solved Problems: Single Degree Free Vibration

In the case of vibrations, the datum position is the mean or equilibrium position at which the potential energy of the body or the system is zero. In the free vibrations, no energy is transferred to the system or from the system. Therefore the summation of kinetic energy and potential energy must be a constant quantity which is same at all the times. In other words, 5. A vertical shaft of 5 mm ...

Physics Tutorial: Vibrational Motion

Wiggles, vibrations, and oscillations are an inseparable part of nature. A vibrating object is repeating its motion over and over again, often in a periodic manner. Given a disturbance from its usual resting or equilibrium position, an object begins to oscillate back and forth. In this Lesson, the concepts of a disturbance, a restoring force, and damping are discussed to explain the nature of ...
