Abstract

The invention discloses a load test board with a sail stress simulation function. Mechanical hardware of the load test board includes a base, an oil tank, a motor, a low-speed large-torque motor, a pinion, a main gear, a gear shaft, a bearing and bearing seat set, a reducer, a coupler, a magnetic powder brake, an encoder and a torque sensor. According to the arrangement, the rotating angle of main gear simulates that of the sail; the magnetic powder brake is used with the reducer to simulate resistance applied onto ship during sailing. A hydraulic system of the load test board comprises the oil tank, the motor, a gear pump, a speed-regulating reversing valve, the motor, a one-way valve, a relief valve, a pressure sensor, a flow sensor and the main gear. The main gear is used for driving a sail rotation simulating mechanism. The load test board has the advantages that under varied wind field conditions, the stress applied onto the sail can be simulated in the real-time manner, structure is simple, operation is reliable, functions are complete, stability is high, and response speed is high.

Description

technical field [0001] The invention relates to loading test equipment in the technical field of mechanical experiments, in particular to a loading test bench for simulating the force of sails. Background technique [0002] Offshore wind resources are abundant, and wind energy has many advantages such as cleanness, renewable, and abundant reserves. Using wind energy as power to aid navigation can not only achieve the purpose of saving fuel and energy, but also reduce greenhouse gas emissions. Therefore, research on ship sail installation technology has important practical significance for energy saving, emission reduction and environmental protection. [0003] However, the wind direction and speed at sea are variable, and not all wind directions are favorable to the navigation of ships. When the heading is determined, it is necessary to adjust the sail to the best windward angle according to different wind directions to facilitate navigation. Therefore, it is necessary to ...
