Product Overview
The YBT6-20T is a large six-degree-of-freedom hydraulic swing platform that provides a repeatable laboratory environment for full-scale equipment testing under rolling conditions. It simultaneously reproduces roll, pitch, yaw, surge, sway and heave, enabling extreme sea-state trials that cannot be performed at sea. Continuous adjustment of swing angle and period, real-time motion measurement, preset and recorded wave spectra, and comprehensive status monitoring make it a complete ship-motion simulation laboratory.
Key Features
- 20-ton payload capacity with six degrees of freedom: roll, pitch, yaw, surge, sway and heave
- Roll ±10° (4 s period), pitch ±8° (5 s) and yaw ±7° (6 s) compound motion
- Translational ranges of ±0.4 m (surge), ±0.8 m (sway) and ±0.15 m (heave)
- Composite attitude accuracy with RMS error ≤0.12 mrad and dynamic position accuracy < 0.005 m
- Attitude and position waveform distortion below 2.5% for faithful sea-state reproduction
- Supports synthetic third-harmonic and recorded wave spectrum replay
