The Current Design Method Of Yacht Main Performance Design Research And Practice

Yacht design as an expensive water entertainment project,at home and abroad have a strong demand.But after a visit to the current yacht design company,we found that most yacht companies in the yacht design,the performance design and no more theoretical basis,by virtue of the designer for many years accumulated experience,so sacrifice is Performance design accuracy and more unpredictable risks.This paper mainly focuses on the main performance design of yacht,and analyzes the main dimensions of the yacht,the stability of yacht,the resistance of the yacht,the propulsion of the yacht,the yacht operation and the slewing performance,the yacht severity and the movement performance.The full text is structured as follows:First of all,we discuss the yacht research background,research significance,the development of yacht at home and abroad,the research status and the main work were introduced.Secondly,we use the mother-type boat fitting method,the main scale of the yacht to fit.The yacht is divided into three categories according to the size of the volume of Fu Ruide,respectively,looking for the three types of yacht mother boat,put the type of width and total length of the fitting formula,draft and total length of the fitting formula.In addition,for the stability of the yacht,respectively,we discuss several aspects of the content,including the static stability curve,cross-stability curve,the impact of free liquid,heavy load impact the stability,The inclination test method and the breaking stability calculation,and according to the actual ship data,the integrity of the stability and damage stability were calculated.Then,in chapter 4,we introduce the method of estimating the empirical formula of yacht resistance estimation,and use XFLOW software to model the yacht,calculate the final resistance result and compare the empirical formula,and draw the conclusion that the empirical formula In terms of estimation,the accuracy is higher.Then,in chapter 5,the handling performance and the rotary performance of the yacht are discussed.The maneuverability is mainly for the rudder,the type,position and calculation coefficient of the rudder system.Calculation,and its rotary performance is mainly calculated yacht radius of rotation.Finally,the paper analyzes the anti-wave and the motion performance of the yacht,introduces the type of wave,expounds the frequency of roll,pitching,attenuation coefficient,the interaction between yacht and wave,and the measures to reduce roll and roll.The dynamic performance of the yacht in the wave is also analyzed.In short,in this article,we explored the main performance when the man design the yacht,the need to think and explore the aspects,and in these areas,I add some examples for designers to refer.
