Electrodynamic shaker working principle

The electrodynamic shaker is one of the key technologies in the field of vibration measurement and measurement. It is a device used to simulate vibrations of various frequencies and amplitudes, designed to ensure that equipment and structures can withstand the vibration forces under actual operating conditions.
The electrodynamic shaker working principle is based on electromagnetic induction. It consists of components such as a voice coil, permanent magnet and armature, through which precise and repeatable vibrations can be generated. These devices are used in many industries, including aerospace, automotive, electronics and the military, to help verify the durability of products under real-world conditions.
In general, the electrodynamic shakers is a device that uses electromagnetic principles to generate controlled vibration, which plays a key role in simulating the real vibration environment and verifying product performance. It provides important tools and means for vibration testing and analysis in various industries.

electrodynamic shaker system working principle

Electrodynamic shaker system is actually an electromagnetic induction principle, when the energized conductor is subjected to resistance in a constant magnetic field, the dynamic coil of the dynamic coil winding is constantly changing and produces vibration, the dynamic coil winding of the electrodynamic shaker system is in a gap of high magnetic induction intensity, and the signal of the shaker is generated from the signal generator or vibration controller and amplified by the power amplifier. At this time, the vibration will produce the desired vibration waveform.

The electrodynamic shaker working principle can be summarized as follows:

Magnetic field generation：The vibrator contains a permanent magnet or electromagnet that generates a constant magnetic field.

Current drive:The vibrator is fitted with a coil called a drive coil. When an AC current is applied to the drive coil, the coil generates an electromagnetic force in a magnetic field.

Vibration generation:The electromagnetic force will drive the piston (or armature) of the vibrator to produce vibration,the shaker is attached to the piston and therefore produces a corresponding vibration.

Amplitude control:the amplitude and frequency of the shaker can be controlled by adjusting the size and frequency of the current in the drive coil.
