2-3 About The Vibration System
(1) Double magnetic circuit structure to ensure high magnetic field
intensity & reduce flux leakage;
Special degaussing structure can reduce flux leakage to below 1 mt
(2) U-type spring ,rollers and linear bearing for strong resistance
of deflecting load
(3) Air spring are used for vibration isolation; Vibration system
work steadily even with heavy load;
no need special foundation
(4) 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
(5) Can complete sine ,random , impact environmental tests
(6) This system has little requires for voltage fluctuation, ≤±10%
is OK
(7) This system has little requires for Grounding resistance, ≤4Ω
is OK
(8) High reliability, especially suitable for long-time running
