Watercooled Vibration Test System
Introduction
1. The watercooled vibration test system is characterized by large force, great bearing capacity, and high cooling efficiency. It is used extensively for testing big components and complete machines in different industries such as aviation, aerospace, shipbuilding, weapons, automobile, etc.
2. This vibration control system is able to accomplish the triaxial sinusoidal vibration test, broadband random vibration test, as well as the classical (semisinusoidal, trapezoidal, and postpeak sawtooth) pulse and shock response spectrum test. Configured with a climate chamber, it can also complete the multienvironment combined test.
3. Thus far, various types of watercooled vibration test system have been provided for option. The exciting force ranges from 50kN to 500kN. The maximum load varies from 800kg to 15000kg.
4. This vibration testing system is composed of the shaker, power amplifier, and the cooling unit. It can be optionally installed with Amber, Vibstar, or other control devices.
Prominent Characteristics
1. Wide Frequency Range and High FirstOrder Resonance Frequency
The watercooled vibration test system adopts highstrength aerospace composites. This will result in great improvement of the strength, stiffness, and firstorder resonance frequency of coil. Also, it allows our product to achieve an international advanced level.
2. HighReliability and EnergyEfficient Excitation Coil
The excitation coil adopts doubledisk winding design to improve its manufacturability and reliability. By adoption of innovative design philosophy, its energy and heating power are enormously reduced.
3. High WaterCooling Efficiency
The watercooled vibration test system has remarkably improved its cooling effect, by employing new welding technique as well as the innovative parallel cooling of both coil winding and internalexternal short circuit ring.
4. Automatic Adjustment of the Armature Balance Position in Use of MPCS Device
The automatic centering system allows the armature to be always in the balance position during movement. Then, a vibration test that requires the maximum displacement can be conducted smoothly.
5. High Bearing Capacity
A combined air spring supports the suspension system to improve its bearing capacity and also reduce ambient noise significantly.
6. Horizontal and Vertical Tests
The watercooled vibration shaker with a slip table is ideal for use in horizontal and vertical vibration tests. It can be overturned conveniently by adoption of unique powerdriven worm wheel and chain wheel.
7. Safety Properties
Our watercooled vibration test system is made in compliance with European standard test requirements. Its power amplifier is equipped with emergency stop button to cope with emergencies in time. It is in compliant with safety requirements of both American UL and CE standard.
Model Selection Guide
The shock test equipment may be affected by the overturning moment, inertia moment, centerofgravity position, and the height of centerofgravity of specimen. Therefore, its safety factory is recommended to be more than 1.2 times as high as theoretical force.
Performance Parameters
1. Highefficiency Watercooling Method
2. Sinusoidal excitation force ranges from 50kN to 500kN.
3. Random to sinusoidal excitation force ratio is 1:1.
4. Twotimesofsine shock force (Three times optional)
5. Displacement peaktopeak value is 51mm, 76mm.
6. Lightweight armature and Large working table
7. An air spring at trunnion position can offer superb vibration isolation effect.
8. Great bearing capacity of air spring in central room, and extraordinary lowfrequency performance
9. An automatic centering system allows the armature to be always controlled in the balance position during movement.
10. Double magnetic circuit design has advantages such as low flux leakage and uniform magnetic field. A slip table can be configured.
11. Horizontal and vertical vibration tests depend on worm wheel transmission to save labor.
12. Available test functions include Sine, Random, and Shock.
13. Efficient and HighReliability Power Amplifier
Note: The power amplifier can be optionally installed with a remote controller and a LCD screen.
