20 kN Exiting Force Electrodynamic Machine for High Frequency
Vibration Testing
Vibration testing is done to introduce a forcing function into a
structure, usually with the use of a vibration test shaker or
vibration testing machine. These induced vibrations, vibration
tests, or shaker tests are used in the laboratory or production
floor for a variety of things, including qualifying products during
design, meeting standards, regulatory qualifications, fatigue
testing, screening products, and evaluating performance.
Applicable Standards: MIL-STD, DIN, ISO, ASTM, IEC, ISTA, GB, GJB, JIS, BS etc.
Applicable Industries: Automotive, Electronics, Aerospace, Vessel, Telecommunication,
Optoelectronics, Instrument etc.
Features:
- Double magnetic circuit structure to ensure high magnetic field
intensity & reduce flux leakage; Special degaussing structure can
reduce flux leakage to below 1 mt
- U-type spring ,rollers and linear bearing for strong resistance of
deflecting load
- Air spring are used for vibration isolation; Vibration system work
steadily even with heavy load; no need special foundation
- Protection devices are provided for over-thermal, over-load,
over-current, over-voltage, and over-displacement of the vibration
tester; Electrical network protection devices for over-voltage,
under-voltage, lacking phase; Drive power , current-limiting ,
soft-start, over-temperature, short-current,module fault protecting
- Able to complete sine ,random , impact environmental tests
- This system requires voltage fluctuation, ≤±10%
- This system requires Grounding resistance, ≤4Ω
- High reliability, especially suitable for long-time operation

Technical Parameters of Horizontal Expander:
Vertical electromagnetic shaker is unable to test the heavy and
large specimen, and the high position of center of gravity will
cause sideslip, tumbling and overturning moment and this will
always overstress the suspension system of shaker and damage the
system. Therefore, need for slip table system for vibration testing
is increasing to allow the testing to be done horizontally so that
the system can withstand larger and heavier load.
