Unidirectional and multidirectionnal vibration

How to chose between unidirectional and multidirectionnal vibrations for typical motovibrator applications ?

You must first determine what oscillation type is necessary for your applications. Generally speaking, free oscillation systems allow to obtain a flow of matter.

Oscillation systems depending on resonance are, nevertheless, subjected to complex requirements. Due to the risks posed by resonance, the application must be perfectly mastered.

Oscillation systems depending on resonance

A resonant system can indeed accumulate energy, if the latter is periodic and closing on a frequency type known as “resonance frequency”.

Through such stimulations, the system will be subject to increasingly important oscillations until it reaches:

  • a balance regime depending on the dissipative elements from the system;

  • a breakage of one of the system’s components.

This synchronization must, consequently, be a voluntary approach, which allows to determine, for instance:

  • the damping capacity of a product; 

  • the breakage threshold of a part.

If your installations are not made to support this, your equipments may suffer damage when the resonance occurs. In this regard, it is strongly recommended to contact the VIBRAXTION technical and commercial support to run a specific and thorough check-up beforehand.

This is why this article only focuses on free oscillation systems, which are the most used in the industry.

Free oscillation systems

Free oscillation systems offer a great variety of amplitudes and vibratory frequencies. Such flexibility allows to meet your needs, according to your application and what materials you employ.

This frequency can even vary on request so it is adapted to specific conditions – on the condition, of course, that it does not induce a resonance effect.

A free oscillation system can be achieved through two methods:

  • Multidirectionnal vibrations: the vibratory force propagates in all directions, in a 360° radius.

  • Unidirectional vibrations: the vibratory force propagates in one direction in time, in an alternating sinusoidal mode.

Unidirectional and multidirectionnal vibrations

The multidirectionnal vibration method only requires one vibrator. The unidirectional method is determined by two vibrators with the same electromagnetic characteristics, that rotate in opposite directions.
