Embodiment Construction

[0015] The specific implementation manners of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0016] First, the true wind measuring device composed of the ultrasonic wind direction and wind speed measurement module 10 and the ship attitude measurement module 11 is fixed on the two-axis linkage ship swing simulation platform; then the wind tunnel wind flow field is set to a constant value, and the ship swing simulation platform is vertically Place it statically, measure the wind direction and wind speed as the reference value for true wind calibration, change the rotation distance and speed parameters of the ship swing simulation platform through the host computer 16, and respectively simulate the roll and pitch motion of the ship at different swing speeds and different swing angles; The ultrasonic wind direction and wind speed measurement module 10 and the ship attitude measurement module 11 transm...

Abstract

The invention belongs to the field of ship engineering, and provides a device for ship true wind measurement and calibration. A transverse swing calibration module and the longitudinal swing calibration module are linked to simulate the spatial movement of the ship body under the disturbance of wind wave flow; the transmission distance and speed parameters of a swing calibration sliding table areadjusted through an upper computer; a ship swing simulation table is controlled to simulate pitching and rolling motions of a ship at different swing speeds and different swing angles, and a ship truewind direction and wind speed calibration database with the swing angles and the swing speeds as variables is formed. The device effectively simulates the transverse and longitudinal swinging motionof a ship, is used for calibrating a ship true wind measurement device, reduces the dynamic measurement error of the wind direction and wind speed in a ship space motion state, and improves the calibration flexibility and reliability of the ship true wind measurement device.

Description

technical field [0001] The invention belongs to the field of ship engineering, in particular to a device for measuring and calibrating true wind of ships. Background technique [0002] Wind speed and direction are important parameters for ship maneuvering and control. Improving the measurement accuracy of ship wind speed and direction is of great significance for safe landing of carrier-based aircraft, emergency rescue and disaster relief, and ship departure from dock. At present, the ship-borne wind sensor generally measures the relative wind, supplemented by the ship's course and speed information to calculate the true wind. However, in addition to being related to the course and speed of the ship, the true wind of the ship is also affected by the spatial motion of the ship such as roll and pitch. This leads to large errors in true wind measurement. By combining the ship attitude sensor with the wind speed and direction measurement sensor to form a true wind measurement ...
