【摘要】:锚唇,作为锚系的一个部件,其表面形态为复杂曲面,而曲面的复杂形态主要归咎于它要满足于一定的运动性能要求。以往锚唇都是通过设计者丰富的经验并配合大量的木模拉锚试验进行曲面设计,这种设计方法不仅费时、费力,还会造成材料的浪费。本文通过对国内外曲面设计技术进行分析,提出一种新的锚唇曲面设计方法。这一方法是基于CATIA二次开发技术,利用共轭包络理论求解出锚杆、锚爪与锚唇接触处的曲面,并利用MATLAB绘图功能绘制出其接触曲面的形状以及获取其曲面上的型值点。以这些型值点为基础,对锚唇曲面进行智能设计。 其次,锚系运动为多刚体接触运动,为了给锚系建立较为合理的动力学模型以便进行正确的拉锚仿真分析,对接触碰撞动力学的知识进行了系统阐述,介绍了ADAMS中接触碰撞力学模型以及接触碰撞判断规则,并利用ADAMS仿真功能分析了锚系运功过程中的主要影响因素,以便于后期的仿真验证。 最后,以10000TEU标箱集装箱船的锚唇为例,利用提出的新的锚唇设计方法对其进行设计。设计完成之后,利用UG的仿真功能对其锚系进行运动仿真分析,验证设计的锚唇是否合理,能否达到设计者的要求。 总之,本文将船舶锚唇设计作为研究方向,并以求解锚杆、锚爪与锚唇曲面接触处的曲面和其曲面上型值点为主要的研究对象进行了具体的阐述,,对实现船舶锚唇智能设计具有一定的参考意义。
[Abstract]:Anchor lip, as a part of anchorage system, its surface shape is complex curved surface, and the complex shape of curved surface is mainly attributed to its motion performance requirements. In the past, anchor lip was designed by the designer's rich experience and cooperated with a large number of wooden model pull anchor test. This design method is not only time-consuming, laborious, but also constructed. This paper presents a new design method of anchor lip surface based on the analysis of surface design technology at home and abroad. This method is based on CATIA secondary development technology, using conjugate envelope theory to solve the surface of the contact between anchor rod, anchor claw and anchor lip, and using MATLAB drawing function to draw the shape of its contact surface. Based on these values, intelligent design of anchor lip surfaces is carried out.
Secondly, the motion of anchorage system is a multi-rigid-body contact motion. In order to establish a more reasonable dynamic model for anchorage system in order to carry out the correct simulation analysis of pulling anchor, the knowledge of contact collision dynamics is systematically expounded. The mechanical model of contact collision and the judgment rules of contact collision in ADAMS are introduced, and the simulation function of ADAMS is used to analyze it. The main influencing factors in the work of anchor system are convenient for later simulation.
Finally, taking the anchor lip of 10 000 TEU container ship as an example, the new design method of anchor lip is used to design the ship. After the design is completed, the motion simulation of the anchor system is carried out by using UG simulation function to verify whether the designed anchor lip is reasonable and can meet the requirements of the designer.
In a word, this paper takes the design of ship's anchor lip as the research direction, and takes the solution of anchor rod, the curved surface of the contact between anchor claw and anchor lip surface and the value points on the curved surface as the main research objects. It has a certain reference significance to realize the intelligent design of ship's anchor lip.
