6级海况下波浪补偿装置平台的机构优化设计

摘要

To shorten the development period of wave compensation device platform, taking a certain type of wind power installation vessel as the resarch object, using Matlab software to calculate the six levels of sea condition respectively change curve of the pop density curve, wave angle, wind power installation vessel's pitch and heave motion curve with the spectral density formula proposed by the marine department of our country. With wind power installation vessel in six levels of sea condition of roll, pitch and heave motion range constraint platform motion range; using genetic algorithm to optimize the platform mechanism, set different parameters of mechanism as the objective function for local optimization, finally give data support for the rational design of the structure of the platform.%为缩短波浪补偿装置平台的研发周期,以某型号风电安装船为研究对象,根据我国海洋部门提出的东海区域谱密度公式,运用Matlab软件分别模拟出6级海况下的波普密度曲线、波倾角变化曲线、该型号风力发电船的横摇、纵摇和升沉运动曲线.具体以风力发电船在6级海况下的横摇、纵摇和升沉运动范围约束平台机构的运动范围,采用遗传算法对平台机构进行优化,分别设定不同机构参数为目标函数进行局部优化,最终为平台结构的合理化设计提供数据支持.
