大型绞吸挖泥船性能提升研究

Performance improvement of large cutter suction dredger

在中长周期波浪海况条件下,针对我国早期研制的大型绞吸挖泥船施工适应性差、长排距工程排距受限等难题。本文以“天杉”船为研究对象,通过理论分析、数值模拟、有限元分析计算、实船验证等方法,开展了大型绞吸挖泥船定位系统性能提升、输送系统性能提升、船舶动力系统升级研究,形成了一系列大型绞吸挖泥船性能提升的技术,并成功应用。为我国早期研制的大型绞吸挖泥船的性能改善提供参考。

Regarding the problems such as poor construction adaptability of the large cutter suction dredgers developed in China under medium and long-term wave sea conditions, and limited row spacing in long row spacing projects. In this study, taking the “Tianshan” ship as a research object, through the theoretical analysis, numerical simulation, finite element analysis and calculation, real ship verification and other methods, we upgrade a series of the performance improvement, including the positioning system, the conveying system, and the power system.The technologies for large cutter suction dredgers, which has been successfully applied. It provides a reference for the performance improvement and transformation of the large cutter suction dredger developed at the early stage in China.
