A Kind of Wave Passive Compensation Device's Rope Tension Research

摘要

In the large water trawler system work process, trawlers are influenced by the marine environment, can produce large movement, which seriously affect the drag efficiency. This study is based on a wave passive compensation device, establish its mathematical model for the simulation analysis, design the test process, extract and analyze the test data. Finally compared with the theoretical analysis results and found that: Wire rope tension change in cycle according to displacement's cycle (caused by external disturbances), displacement has different trend with the rope tension. When the displacement amplitude is in less than 50 mm, rope tension keep stable; Suffered the effect of inertia force, the speeds of tension change in different stages. By the simulation analysis, the larger the gas pressure of accumulator in the equilibrium position, the greater the tension; The larger the accumulator's area, the smaller the tension.
