Description

Air Cooled Shaker

The air-cooled series electro-dynamic vibration test system has the advantages, such as wide frequency range, excellent indicators, high reliability, small floor space, easy to move, and easy to operate. At present, this series has a variety of models of vibration generators to choose. The exciting force range is from 1kN to 70kN and maximum load is from 70 kg to 1000 kg. Also, the climate and mechanics environmental testing equipments are provided.

Performance characteristics

Sinusoidal excitation force range: 1kN ~ 70kN

Random to sinusoidal excitation force ratio 1:1

Two-times-of-sine shock force (Three times optional)

Displacement peak-to-peak value of 25mm, 40mm, 51mm, 76mm or 100mm
