Electrodynamic Shaker - Water Cooled

Water-cooled electrodynamic shaker vibration test systems feature large force, large bearing capacity and high cooling efficiency.  The exciting force range is from 50 kN to 600 kN and the maximum load is from 800 kg to 15000 kg.Water cooled, high-excitation force shaker systems are used to test some of the most complex and demanding products including entire satellites and hazardous materials to integrated electronic systems and other large parts used in aviation, aerospace, shipbuilding, military, and automotive applications. A multi-environment combined test can be completed with an optional climate chamber.

Our water-cooled vibration test 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.

Compared to air-cooled vibration testing systems, Dongling’s water-cooled equipment is able to accommodate larger parts, generate bigger force and operate more quietly.

All water-cooled Dongling vibration testing systems include the shaker, power amplifier, and cooling unit. Controllers from all 3rd party vendors as well as the Amber and Vibstar controllers from Dongling are all compatible with the Dongling vibration test systems.

Features:

  • Made From High Strength Composites: Our water-cooled vibration test system is manufactured from high-strength aerospace composites guaranteeing extremely high strength, stiffness, and first-order resonance frequency of test coils.
  • Double-Disk Winding Design: The double-disk winding design of the exciting coil provides extremely high reliability performance while simultaneously improving its energy efficiency and reducing the amount of heat produced.
  • High Efficiency Cooling: Our system has been designed from the top down to maximize cooling efficiency, from employing new welding techniques to combining in parallel the cooling of both coil winding and internal-external short circuit ring.
  • Automatically Centering and Balancing Armature: The automatic centering system allows the armature to maintain balance throughout its full range of motion, ensuring that vibration tests can be conducted smoothly even at maximum displacements.
  • High Bearing Capacity Suspension: Dongling’s water-cooled vibration test system employs a combined air spring to provide optimal suspension support while signifantly reducing ambiet noise levels in the testing environment.
  • Test both Horizontal and Vertical Orientations: The water-cooled vibration test system with a slip table can be used for horizontal and vertical tests. It provides convenient access for overturning parts and also provides simple dual-direction switching mode
  • UL and CE Certified: Dongling Vibration Test machinery comes complete with American and European-certified safety features, including an emergency stop button and electronics certified by Underwriter’s Laboratory.
