Electrodynamic Shaker with Vibration Controller and Power Amplifier

The mode of function of a shaker corresponds to that of a loudspeaker. The vibration movement is generated by the interaction of electric current passing through the plunger coil and a magnetic field. The force used to accelerate the moving element comprised of a ribbed body and the wrapped plunger coil is proportional to the coil current, the magnetic flux density, and the length of conductor in the magnetic field. The vibration level of shaker can therefore be controlled by electric current intensity.

Meet Standards:

MIL-STD, DIN, ISO, ASTM, IEC, ISTA, GB, GJB, JIS, BS etc.

Applicable Industries:

Automotive electronics device, Motormeter assembly, Automobile storage battery, Automotive electric equipments, Automotivemotor, Water-soluble dielectric battery, Safety valve, Auto air conditioning compressor 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.
