Air-Cooled Force: 30kN ~ 53kN
Shipboard shock, transportation and package test requirements require high velocity and large displacement performance. 1g Dynamics D30 long-stroke (LS) Series vibration systems are designed for test requirements normally performed by servo-hydraulic shakers. Compared to a servo-hydraulic shaker where the maximum test frequency is limited, the D30LS Series is capable of up to 2500 Hz.
- Velocity sine force 2.4 m/s
- Max Displacement 100 mm
- Payload capability up to 800 kg
- Automatic dynamic armature centering
- Rugged air-isolated trunnion
Available options:
- Air-isolation feet, pads or mounts
- Motorised gearbox for vibrator rotation
- Wide-range of mono-base slip tables
- Thermal barriers for use with climatic chambers
- Cast and fabricated head expanders & fixtures
