Product Description:
The working principle of the
electromagnetic vibration exciter is similar to a loudspeaker whereby electrical conductor is moved
by the action of electromagnetic force in the magnetic field. The
force to accelerate the moving part is generated by the balance
between driving current and magnetic flux. Therefore, by
controlling the driving current, one can control of the vibration
generator.
The maximum acceleration level of the electromagnetic vibration
exciter is determined by the maximum current and the load. At low
frequency, displacement of moving part will impose a limitation and
the acceleration will not reach high level. The resonance frequency
of the moving element is set higher than the upper limit of the
frequency range.

Applications:
EV series electromagnetic vibration testing system simulates the
vibration environment under the laboratory condition, and test the
impact strength as well as reliability of various vibration test
applications. In the laboratory, with the aid of vibration testing
system, model simulation of reproduction of sinusoidal, random,
resonant search and dwell, classical shock and road simulation,
etc. can be achieved. It is essential for product quality
assurance, new product research and development
EV series electromagnetic vibration testing system is specially
designed to meet the need for long time operation, installation of
vibration resistant base can achieve vertical and horizontal
vibration. The standard platform is installed with high efficiency
airbag shock isolation device so that the vibration transmitted to
the building can be minimized, at the same time avoid the need of
additional foundation in most of the cases.
A complete set of vibration testing system is composed of shaker,
power amplifier and vibration measuring control system, in
accordance with the relevant national and international standards
(such as: MIL-STD, DIN, ISO, ASTM, IEC, ISTA, GB, GJB, JIS, BS,
etc.) to provide technical support for establishing product quality
inspection.
Customization:
Customization is available. For example the size of the head
expander and slip tabel can be customized accroding to the test
sample.
