Principle

18. Mechanical Vibration

a. Set an object into oscillation
b. If oscillation exists, increase its frequency, even as far

as ultrasonic

c. Use the frequency of resonance
d. Instead of mechanical vibrations, use piezovibrators
e. Use ultrasonic vibrations in conjunction with an electromatic

field

Principle Description: Use vibration or oscillations to involve a regular, periodic variation in value about a mean.

Hints on Usage: Consider the many ways to use vibration or oscillation:

- Cause an object to oscillate or vibrate.
- Change the degree of vibration or oscillation (frequency or

amplitude).

- Alter the frequency to the ultrasonic level.
- Utilize an object’s resonant frequency.
- Transition mechanical vibration to piezoelectric vibrators.
- Combine ultrasonic (mechanical fields) and electromagnetic

fields.

But don’t stop there. Look at this principle a little deeper; it delivers more than mechanical vibration especially if combined with Principle 15 (Dynamicity) and/or Principle 19 (Periodic Action). For example, shifting from direct current to alternating current creates new features such as electromagnetic waves, electromagnetic inductions, etc.

Also, do not assume a stable system is best. Explore the benefits of a system with controlled instability or variation.

Examples:

Phonograph records are played when a needle follows a groove which has a shape modulated by sound waves. The needle vibrates in the same pattern as was used to cut the groove and this vibration is amplified and output through loudspeakers.

A tape recorder uses a thin strip of plastic tape coated with a magnetic material which passes by an electromagnet. The electromagnet is modulated by the sound wave, creating magnetic patterns on the tape. Reversing the process, the tape moves past a coil in which the changing magnetic patterns induce an electric current, which is then amplified back to produce the original sound.

Some Native Americans use drum vibrations or chanting to create consciousness-altering states and healing modalities.

Businesses utilize negotiation techniques (inducing variation) to reveal a partner’s real needs. By changing approaches several times they can get a better picture of how all needs fit within the negotiating party.

Vibratory feeders are used to move parts.

Vibration is used to remove burrs from machined parts.

Fluidized beds are used to transfer and process parts at the same time.

Vibration is used to provide a sense of motion in some products.

By passing a number of different tests and rigors (oscillation), police officer candidates become qualified for hire.

Striking a ductile iron casting causes it to vibrate. Measuring the frequency of the vibration indicates the metallurgical quality of the casting – the same use of vibration can be used by striking an antique plate or glass object to determine if the object has been broken.
