Description
The YBT6-20T provides a laboratory platform for repeated testing to uncover and resolve system issues under sway conditions, enabling extreme-sea-state tests that cannot be performed at sea. Multi-mode test equipment for inertial systems, sensors and electro-optical payloads.
The YBT6-20T provides a laboratory platform for repeated testing to uncover and resolve system issues under sway conditions, enabling extreme-sea-state tests that cannot be performed at sea. It offers motion control, run monitoring, hydraulic source control, continuous adjustment of sway angle and period, real-time measurement of angular and translational displacement, synthetic 3rd-harmonic and recorded-spectrum rocking modes, and comprehensive status display. Repetitive sway-condition testing and extreme-sea-state simulation of equipment in the laboratory. The equipment uses an industrial control computer for motion control with direct-drive torque motors and inductosyn or grating angle feedback (where applicable), providing high-accuracy positioning, stable rates, low waveform distortion and high repeatability. Customization is available on request. All specifications are transcribed from the manufacturer’s product brochure.
