The Water-cooled Electro-Dynamic Vibration Test Table has large thrust force , strong carrying capacity and high cooling efficiency. Tri-axial sinusoidal vibration tests, broadband random vibration tests, and classical shock test like (half sine wave , trapezoidal wave , post-peak wave ) pulse and shock response spectrum tests can be performed separately. The climate chamber can be configured to complete a multi-environment comprehensive test with temperature and humididty environmental test . There are currently varied models of shakers available in this range. The excitation force ranges from 50kN to 400kN and the maximum load ranges from 800kg to 6000kg.
Performance characteristics
1 Random and sinusoidal excitation force: 1:1
2 Twice the sinusoidal impact (optional three times)
3 Displacement peak-to-peak: 51mm, 76mm or 100mm
4 The moving coil is light in weight and the work surface is large.
5 The air spring of the trunnion has good vibration isolation effect.
6 Dual magnetic circuit design, low magnetic flux leakage, uniform magnetic field.
7 Configuration of electric steering device when switching between horizontal and vertical.
Product Features
