Aerospace vibration table testing

Electromagnetic vibration table is a testing equipment that uses the principle of electromagnetic induction to generate precise and controllable vibrations. Its core is driven by the force movement of the energized coil (moving coil) in a constant magnetic field, thereby driving the vibration of the table.

1Aerospace vibration table testingmain purpose

It is mainly used for environmental adaptability, reliability, and durability testing of products, and is widely used in:

Reliability testing: During the research and development phase, simulate the vibration environment that products may encounter during transportation, installation, and use, discover design defects, and improve product quality.

Environmental Stress Screening (ESS): Apply vibration stress to batch products on the production line to eliminate early faulty products.

Structural strength test: Evaluate the mechanical strength, fatigue life, and dynamic characteristics of the specimen.

Scientific research: used for studying material properties, structural dynamic response, and other related topics.

IIAerospace vibration table testingcore functionality

Accurate reproduction of vibration: capable of accurately simulating various waveforms such as sine fixed frequency, sine sweep frequency, random vibration, and classical impact.

Broadband testing: The operating frequency range is extremely wide, ranging from a few Hz to several thousand Hz, meeting the vast majority of vibration testing needs.

High acceleration implementation: It can generate high acceleration and is suitable for stress testing under harsh conditions.

Closed loop control: Real time monitoring of table vibration using sensors, and feedback adjustment through the control system to ensure the accuracy and stability of vibration values.

3、 Outstanding features

Excellent performance: low waveform distortion, high control accuracy, low noise, capable of achieving complex random vibration testing.

High flexibility: Driven by electrical signals, various waveforms and test profiles can be easily programmed to adapt to different testing standards.

Wide thrust range: The equipment thrust ranges from tens of newtons to tens of thousands of newtons, and can test specimens of different specifications from small electronic components to large vehicle parts.

Relatively complex maintenance: requires supporting power amplifiers, cooling systems, etc., with higher equipment costs and maintenance requirements than mechanical vibration tables.

Electromagnetic vibration table is an important precision testing instrument in modern industry and scientific research. It provides key technical support for ensuring the reliability and quality of products in dynamic environments with its control performance, extensive testing capabilities, and high flexibility.
