海洋环境监测平台数据采集吊舱减摇装置动力学分析与试验
Dynamic analysis and experiment of anti-rolling device for data acquisition pod of marine environment monitoring platform
摘要
Abstract
With the in-depth development of marine ranching construction,environmental monitoring platforms have been widely used in the monitoring of mariculture environments in marine ranches.In view of the problem of cable breakage and damage that occurs during the deployment and recovery process of the data acquisition pod of the marine environmental monitoring platform used in production due to the influence of wind,waves and currents.A pod anti-rolling device for offshore platforms is designed.Based on Newton's second law,a dynamic model of the pod anti-rolling device under the excitation of rolling and pitching of the offshore platform is established and numerical simulation analysis was carried out using Matlab/Simulink software,and the changes in the swing amplitude of the pod with and without the anti-rolling device were compared.The results show that in the case of having an anti-rolling device,the swing amplitude of the in-plane angle of the pod can be reduced by about 66.9%,and the swing amplitude of the out-of-plane angle can be reduced by about 69%.The average anti-rolling ratio is 67.95%.Based on the existing theory,an experimental prototype was built and tested for verification.The test results show that the pod anti-rolling device has an obvious restraining effect on the swing amplitude of the pod.The swing amplitude of the in-plane angle can be reduced by about 73.5%.The research shows that the pod anti-rolling device has important practical guiding significance for improving the reliability and safety of the data acquisition system of the marine ranch monitoring platform.关键词
