Product Description

Product Description

Water Cooled Shaker
Water-cooled vibration test system features with the large force, large bearing capacity and high cooling efficiency, to complete the tri-axial sinusoidal vibration test, broadband random vibration test and classical (semisinusoidal, trapezoidal, and postpeak sawtooth) pulse and shock response spectrum test. The multi-environment combined test can be completed with the equipped climate chamber. At present, this series has a variety of models to choose. The exciting force range is from 50 kN to 500 kN and maximum load is from 800 kg to 10000 kg.

Performance characteristics
1.Random to sinusoidal excitation force ratio: 1:1
2.Two-times-of-sine shock force (Three times optional)
3.Displacement peak-to-peak: 51mm, 76mm or 100mm
4.Lightweight armature and large working table
5.Better vibration isolation effect of air spring at trunnion position
6.Large bearing capacity of air spring in central room, andgoodlow-frequency performance
7.Equipped with an automatic centering system, to control the armature is always in the balance position during movement
8.Double magnetic circuit design, with low flux leakage and uniform magnetic field
9.Electric power rotating mechanism is configured forhorizontal and vertical switching
