High-Frequency Electrodynamic Vibration Table System For Aerospace And Electronics Testing

High-Frequency Electrodynamic Vibration Table System For Aerospace And Electronics Testing​
 

System Composition
 

A complete vibration testing system typically comprises three core components:

1. Vibration Excitation Unit: The core is the vibration table (electric, hydraulic, electromagnetic, etc.), responsible for generating vibration signals with a set frequency, amplitude, and acceleration.

2. Measurement and Control Unit: Includes a signal generator, power amplifier, and measurement and control software, used to set test parameters (such as sinusoidal vibration, random vibration, impact vibration, etc.), acquire vibration data, and perform real-time closed-loop control of the vibration table output.

3. Auxiliary Units: Such as fixtures (to fix the test piece), cooling system (to ensure long-term equipment operation), and safety protection devices (to prevent test piece from falling off or equipment malfunction).

Key Features
 

1. Highly Controllable Vibration Parameters
Precisely adjusts the vibration frequency range (from a few Hz to tens of thousands of Hz, covering low-frequency transportation vibration to high-frequency mechanical vibration), amplitude/acceleration (meeting different product testing standards), and vibration waveform (supports various waveforms such as sine waves, random waves, shock waves, and frequency sweep waves), simulating single or complex vibration environments.
 

2. Diverse Test Modes
Adapts to different testing needs. Common modes include:
Sine Vibration Test: Simulates steady-state vibration of rotating machinery (such as motors and engines) to test the product's resonance point;
Random Vibration Test: Simulates irregular vibrations such as those from transportation, earthquakes, and wind loads, more closely resembling real-world working conditions;
Impact Vibration Test: Simulates instantaneous strong impacts such as collisions and drops to evaluate the product's impact resistance.
 

3. High Precision and High Reliability
Utilizes closed-loop measurement and control technology, resulting in minimal deviation between the actual output value and the set value of vibration parameters; the equipment itself possesses high load capacity and long-term continuous operation capability, meeting the reliability testing requirements of batch products.

4. Compatibility and Expandability: It can be adapted to test pieces of different sizes and weights (from small electronic components to complete automobiles and aerospace equipment) by changing different fixtures; some systems can integrate temperature, humidity and other modules to realize comprehensive environmental testing of temperature, humidity and vibration.
