Abstract

The invention provides a large-amplitude motion follow-up five-degree-of-freedom airworthiness instrument, which comprises a frame, wherein transverse guide rails are arranged at the two ends of the frame, and are provided with transverse moving trolleys; transverse motion measuring devices are arranged on the end parts of the transverse guide rails; a longitudinal guide rail is arranged between end part connecting plates of the two transverse moving trolleys; two longitudinal moving trolleys are arranged on the longitudinal guide rail; longitudinal oscillation measuring and converting devices are arranged at the two ends of the longitudinal guide rail; heaving motion measuring rod guide devices are arranged on the upper and lower parts of the two longitudinal moving trolleys; heaving measuring and converting devices are arranged on the two longitudinal moving trolleys; transverse swinging and longitudinal swinging measuring devices are arranged at the lower ends of heaving motion measuring rods. By adopting the large-amplitude motion follow-up five-degree-of-freedom airworthiness instrument, course stability control and multi-degree-of-freedom motion measurement can be performed on a self-propulsion model under wave facing and oblique wave conditions on the premise of little constrains on a model, and the influence on motion of each degree of freedom of the model is little.

Description

technical field [0001] The invention relates to a model test device used in the technical field of ships and ocean engineering, and is particularly suitable for a multi-degree-of-freedom motion response measuring device for test models of ships and ocean engineering structures. Background technique [0002] In the existing model tests of ships and marine structures, the contact measurement of multi-degree-of-freedom motion response must be completed with the help of airworthiness instruments. The constraints of the model cannot reflect the real motion posture of the test model well. At the same time, the existing four-degree-of-freedom airworthiness instrument cannot complete the measurement of the sway degree of freedom in the structure model test, nor can it complete the model test of the structure model under the oblique wave condition at a certain speed, and is only suitable for facing There are certain limitations in the use of the measurement of the tow test motion of...
