Air-cooled Vibration Test System

Characteristics

1. The air-cooled vibration test system has features of high first-order resonance frequency and wide frequency range.

2. High Reliability of Armature Winding
Innovative technique and structure of the reinforced ring of armature winding has significantly improved vibration resistance under conditions of large forces, high-acceleration vibration, huge impact, and high temperature.

3. High-Efficiency Air Cooling Effect
The air-cooling duct of our air-cooled vibration test system is also innovatively designed to greatly improve its cooling effect. Its top-down magnetic rings respectively adopt the long-groove air-inlet duct, double-layered diffluent duct, and the tapered-wedge air duct. Its excitation coil utilizes a honeycombed air duct.

4. Air-Cooled Blower
Unique air duct and other structural design of our vibration testing systems allow the air-cooled blower to provide low noise and superb cooling effect.

5. Horizontal and Vertical Tests
The air-cooled vibration test system with a slip table can be used for horizontal and vertical tests. It is convenient to overturn, and also provides simple dual-direction switching mode.

6. Power Amplifier with MOSFET or IGBT Module
The power amplifier of our test equipment adopts high-performance MOSFET or IGBT module, thus featuring ultra high stability and reliability.

7. Safety Performance
Our air-cooled vibration test system conforms to European standard test requirements. Its power amplifier is installed with emergency stop button to timely cope with emergencies. It can meet the safety requirements of both American UL and European CE standards.

Model Selection Guide

The air-cooled vibration test system is easily affected by the overturning moment, inertia moment, center-of-gravity position, and the height of center of gravity of specimen. Hence, we suggest that the safety factor should be more than 1.2 times as high as theoretical thrust. A vibration controller is selectable in accordance with test requirements and future development trend.

Performance Parameters Forced-air cooling Sinusoidal excitation force range is from 1kN to 70kN. Random to sinusoidal excitation force ratio is 1:1. Two-times-of-sine shock force (Three times optional) Displacement peak-to-peak value: 25mm, 40mm, 51mm, 76mm, or 100mm. The lightweight armature features optimization design and strong vibration-resistant performance. The air spring at trunnion position gives outstanding vibration isolation effect. Strong bearing capacity of air spring in central room, and excellent low-frequency performance Double magnetic circuit design offers low flux leakage and uniform magnetic field. Available test functions include Sine, Random, Shock, and more. Superb cooling effect and Low noise Highly efficient and reliable power amplifier Parameter List
