Floating gate physical model test device and multi-degree-of-freedom operating method

Abstract

The invention relates to a floating gate physical model test device and a multi-degree-of-freedom operating method, and belongs to the technical field of ship and marine engineering and engineering experiments and tests. The characteristics lie in that a square bracket mechanism of the test device is placed in a moonpool of a trailer mechanism, rollers of a dual-axis disk mechanism are respectively placed in groove guide rails of longitudinal beams on the square bracket mechanism, and a force measurement mechanism is connected with an outer sleeve of the dual-axis disk mechanism and a straight plate on a lower beam of the square bracket mechanism through a steel wire rope of a pulling force instrument, so that the upper end is connected with the square bracket mechanism and a guide rod mechanism through the dual-axis disk mechanism, and the lower end is connected with the square bracket mechanism and the guide rod mechanism through the force measurement mechanism; and a signal receiving terminal of a numerical value collection mechanism and a signal transmitting terminal of the force measurement mechanism perform data communication therebetween. The test device has a multi-degree-of-freedom model guidance function so as to meet flow measurement requirements of a floating gate model under multi-flow-angle conditions. In addition, the test device is simple in structure, convenient to assemble and easy to maintain, and can be applied to water flow force characteristic tests of other floating structures.

Description

technical field [0001] The invention relates to a floating gate physical model test device and a multi-degree-of-freedom working method, which belong to the technical field of ship and marine engineering and engineering test testing. Background technique [0002] The ship test towing tank is an important equipment for the rapid test of the hull model, which is used to measure the hull resistance and motion attitude, and provide the basis for the optimal design of the ship shape. Usually, the water in the towed pool is in a static or wave-making state and has no flow-making function. However, in a static pool, the water flow velocity can be simulated by the movement of the trailer, and the water flow direction can be simulated by placing the test model orientation. The trailer mechanism of the conventional towing tank does not have the function of flow force measurement under multi-flow angle conditions. Therefore, if you want to test the flow characteristics of the floating ...

Problems solved by technology

The trailer mechanism of the conventional towing tank does not have the function of flow force measurement under multi-flow angle conditions. Therefore, if you want to test the flow characteristics of the floating gate model in the ship towing tank, you need to invent and design a model with multiple degrees of freedom. A special device with guiding function to meet the flow force measurement needs of the floating gate model under the condition of multiple flow angles
