3. Designed with a climate chamber, a range of environmental conditions can be simulated to realize various environmental tests. Various vibration tables are available to meet different application needs.

4. The vibration simulating test system comes with an excitation force range from 25kN to 600kN, and the load ranges from 300kg to 15000kg.

Model Selection Guide

Wide Frequency Range and High First-Order Resonance Frequency
The water-cooled vibration test system adopts high-strength aerospace composites. This will result in great improvement of the strength, stiffness, and first-order resonance frequency of coil. Also, it allows our product to achieve an international advanced level.

High-Reliability and Energy-Efficient Excitation Coil
The excitation coil adopts double-disk winding design to improve its manufacturability and reliability. By adoption of innovative design philosophy, its energy and heating power are enormously reduced.

High Water-Cooling Efficiency
The water-cooled 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 internal-external short circuit ring.

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.

High Bearing Capacity
A combined air spring supports the suspension system to improve its bearing capacity and also reduce ambient noise significantly.

Horizontal and Vertical Tests
The water-cooled 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 power-driven worm wheel and chain wheel.

Safety Properties
Our water-cooled 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, center-of-gravity position, and the height of center-of-gravity of specimen. Therefore, its safety factory is recommended to be more than 1.2 times as high as theoretical force.

Performance Parameters High-efficiency Water-cooling Method Sinusoidal excitation force ranges from 50kN to 500kN. Random to sinusoidal excitation force ratio is 1:1. Two-times-of-sine shock force (Three times optional) Displacement peak-to-peak value is 51mm, 76mm. Lightweight armature and Large working table An air spring at trunnion position can offer superb vibration isolation effect. Great bearing capacity of air spring in central room, and extraordinary low-frequency performance An automatic centering system allows the armature to be always controlled in the balance position during movement. Double magnetic circuit design has advantages such as low flux leakage and uniform magnetic field. A slip table can be configured. Horizontal and vertical vibration tests depend on worm wheel transmission to save labor. Available test functions include Sine, Random, and Shock. Efficient and High-Reliability Power Amplifier

Note: The power amplifier can be optionally installed with a remote controller and a LCD screen.
