Vibration System

Application

Water-cooled vibration test systems features with large force, large bearing capacity and high cooling efficiency. The exciting force range is from 25 kN to 600 kN and maximum load is from 300 kg to 15000 kg. Water-cooled vibration test systems are used to test some of the most complex and demanding products in areas of aviation, aerospace, automotive, shipbuilding, defense, and electronics, etc.

Water-cooled systems are capable of performing a variety of vibration test protocols, including: tri-axial sinusoidal vibration test, broad-band random vibration test, as well as the classical (semi-sinusoidal, trapezoidal, and post-peak sawtooth) pulse and shock response spectrum tests. When configured with an optional climate chamber, water-cooled vibration test systems can also perform multi-environment combined vibration tests.

Features

  • Random to sinusoidal excitation force ratio: 1:1;

  • Two-times of sine shock force (Three times optional);

  • Displacement peak-to-peak: 51mm, 76mm or 100mm;

  • Lightweight armature and large working table;

  • Better vibration isolation effect of the air spring at trunnion position;

  • High bearing capacity of center air spring support and good low-frequency performance;

  • Equipped with an automatic centering system, to ensure the armature is always in a balanced position during movement;

  • Double magnetic circuit design, with low flux leakage and uniform magnetic field;

  • Electric power rotating mechanism is configured for horizontal and vertical switching;
