波浪被动补偿装置的模型与实验
Model and experiments of wave passive compensation device
摘要
Abstract
In the work process of the towing system of a large medium-water trawler, fishing boats are influenced by the marine environment and can generate significant movement .To address the reduced fishing efficiency caused by the mov-ing ship, this study used a new wave passive compensation device , studied the mathematical model of the device , and conducted a simulative analysis .The test process was designed , and the test data were analyzed .A comparison with the-oretical analysis results shows that the tension of wire rope and the pressure intensity of the energy accumulator change cyclically follow the displacement of the oil cylinder , and the displacement of the oil cylinder changes in reverse follow-ing the change in rope tension and the pressure intensity of the accumulator .Moreover , the change amplitude of the ten-sion of wire rope is greater than that of the pressure intensity of the accumulator .However, when the change amplitude of displacement is less than 50 mm, the tension (<5 N) and the pressure intensity (<6 Pa) remain stable;the speed of tension changes in stages as a result of inertia force .Simulation analysis shows that a great charging pressure intensity of the energy accumulator at the equilibrium position corresponds to great tension and pressure intensity , and a large area of the energy accumulator corresponds to small tension and pressure intensity .关键词
