The water-cooled electric vibration system has large thrust, strong carrying capacity and high cooling efficiency. Triaxial sinusoidal vibration tests, wideband random vibration tests, and classical (half sine, trapezoidal, posterior peak) pulse and shock response spectrum tests can be performed separately. The climate chamber can be configured to complete a multi-environment comprehensive test. There are currently several 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 The air spring of the central room has strong carrying capacity and good low frequency performance.
7 Equipped with automatic centering system, the control moving coil is always in equilibrium when moving.
8 Dual magnetic circuit design, low magnetic flux leakage, uniform magnetic field.
9 Configuration of electric steering device when switching between horizontal and vertical.
