Dynamics and Vibrations: Notes: Multi-DOF vibrations

5.5.2 Natural frequencies and mode shapes for undamped linear systems with many degrees of freedom. First, let's review the definition of natural frequencies and mode shapes. Recall that we can set a system vibrating by displacing it slightly from its static equilibrium position, and then releasing it.

Linear Technology | Thomas by Gardner Denver

Linear and vibrating armature pumps and compressors utilize electromagnetism to apply force to a diaphragm or piston positively displacing air. Alternating current in electrical coils reverse the magnetic field induced around a magnetized rod at a rate determined by the supplied frequency.

Linear Vibration Welding - an overview | ScienceDirect Topics

In linear vibration welding, the surfaces to be joined are rubbed together in an oscillating, linear motion under pressure applied at a 90° angle to the vibration. Process parameters are the amplitude and frequency of this motion (weld amplitude and weld frequency), weld pressure, and weld time, all of which affect the strength of the ...

Molecular vibration - Wikipedia

A molecular vibration occurs when atoms in a molecule are in periodic motion while the molecule as a whole has constant translational and rotational motion. The frequency of the periodic motion is known as a vibration frequency, and the typical frequencies of molecular vibrations range from less than 10 13 to approximately 10 14 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm ...

Fundamentals of Vibration - Newport Corporation

A simple example of harmonic motion is a mass connected to a flexible cantilevered beam. External force, either from a one-time impulse or from a periodic force such as vibration, will cause the system to resonate as the spring alternately stores and imparts energy to the moving mass.

Linear Vibration vs Pivotal Oscillation

Linear vibration machine is noisy on high frequency. Vibration also generates sound wave. When the frequency is above 20Hz, the sound wave becomes audible. Pivotal oscillation machines, because of low vibration frequency, do not produce a lot of noise.
