Electrodynamic Vibration Test System
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

Digital Vibration Controller
Vibration controller is the latest design by our company
that adopts international advanced distributed system
architecture, and its core is the latest TMS320 series
32-bit floating-point high-speed processor of TI
company. Test report is automatically generated in
Microsoft Word. During or after the testing, the
test report can be edited, and then generated
automatically or manually.
