Electro-dynamic Vibration Test System ·Air-cooled Series

  • 微信或QQ扫一扫

Dongling is one of the largest and most innovative manufacturers of Air Cooled Vibration Testing Systems. With random sine force ratings from 1kN to 70 kN and maximum payloads from 70kg to as much as 1;000kg. Typical applications of Dongling’s air-cooled electro-dynamic shakers include automotive component testing, electronics product testing, avionics testing and medical research, etc.
All air-cooled electro-dynamic shakers can be mounted on a single integrated base with a slip table to meet your testing requirements. DONGLING also provides turn-key solutions including combined environmental chambers, head expanders and fixtures should you require them.

Performance Characteristics

  • Sinusoidal excitation force range: 1kN ~ 70kN
  • Random to sinusoidal excitation force ratio 1:1
  • Two-times-sine shock force (Three times optional)
  • Displacement peak-to-peak value of 25mm, 40mm; 51 mm, 76mm or 100mm
  • Lightweight armature with optimized design and good vibration-resistant performance with excellent vibration isolation with the air spring at the trunnion position
  • High weight bearing capacity of center air spring support and good low-frequency performance
  • Equipped with an automatic centering system, to ensure the armature is always in a balanced position during movement
  • Double magnetic circuit design with low flux leakage and uniform magnetic field
  • Sine, Random and Shock etc. test function capabilities
  • Good cooling effect and low noise blower
