free vibration

We seek to find the free vibration modes of the plate.

Free vibrations are the natural or normal modes of vibration for a substance.

This sets up a positive feedback loop exciting the structure's free vibration.

Experiments with free vibration of light roofs backed by cavities.

When such a relation exists the free vibration asserts itself easily and prominently.

Evaluation of wood poles using a free vibration technique.

All three stressed that the mouthpiece should be placed higher on the top lip for a more free vibration of the lips.

Free vibration single degree of freedom systems.

As an example, the free vibration of a beam can be accounted for by using the load function:

In the absence of a transverse load, , we have the free vibration equation.

Both free vibration and forced vibration simulating earthquake loading were carried out.

Free vibration occurs when a mechanical system is set in motion with an initial input and allowed to vibrate freely.

The special molding, gradually tapering from the center to the edge, provides great flexibility and freer vibration across the board.

The effects of nonstructural mass, pier–water interaction and foundation flexibility on free vibration behavior are also studied by means of the frame model.

The developed code is used to study the free vibration characteristics of stepped, spring supported and twisted beams of solid sections.

In the following analysis involves the case where there is no damping and no applied forces (i.e. free vibration).

A properly adjusted damping factor can control this free vibration of the moving structures and improve the sound of the driver.

Using this coordinate transformation in the original free vibration differential equation results in the following equation.

But when the impressed vibration is very large and the coil's own momentum small, the free vibration can not assert itself readily.

A study of the mechanical damping and shear modulus under free vibration can be made using a torsional pendulum.

The natural frequency and damping ratio are not only important in free vibration, but also characterize how a system behaves under forced vibration.

Free Vibration Simulation Applet Enter values for the 5 inputs in consistent units.

Free vibrations of any elastic body is called natural vibration and happens at a frequency called natural frequency.

The goal of modal analysis in structural mechanics is to determine the natural mode shapes and frequencies of an object or structure during free vibration.
