基于共轭包络的船舶锚唇曲面设计技术研究
|
摘要
为了改变锚唇曲面的传统设计方法,提出了一种新的设计思路.根据预期的拉锚时锚杆和锚爪与锚唇接触的运动轨迹,通过共轭包络原理推导出它们与锚唇接触处的曲面方程,利用MATLAB生成该曲面并获取其型值点,然后基于型值点完成整个锚唇曲面的设计.最后以30万吨超大型油轮的锚唇为例,利用该方法进行设计并验证其结果的有效性.
This paper proposes a new kind of design to change the traditional design method of anchor mouth surface. Curved surface equation is derived by the conjugate envelope theory according to anchor stock motion track relative to anchor palm and anchor mouth. Surface shape points are obtained by use of MATLAB software and the anchor mouth surface design is finished. Finally,an example of the VLCC's anchor mouth design is given to verify the result.
