Electro-dynamic Vibration Test System ·Water-cooled Series

  • 微信或QQ扫一扫

Water-cooled electro-dynamic shaker vibration test systems feature large force, large bearing capacity and high cooling efficiency. The exciting force range is from 25 kN to 600 kN and the maximum load is from 300 kg to 15,000 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, our water-cooled vibration test systems can also perform multi-environment combined vibration tests.
