32kN Sine and Random Force Vibration Test System 1400*900*1100 mm , 500 kg Payload

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

Specifications: EV232-EV330

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.
