Design system for ship block lifting with computer aided

To improve the working efficiency of designers in block lifting and to change current status of manual design,the automated design system for ship lifting draft was developed.Based on the analysis of characteristics and condition of block lifting,the principles and requirements of lifting draft were summarized.Models for lifting objects and equipment were constructed,and the automated design algorithm and the system functional structure were also put forward.With simple and intuitive visual user interface,the system provided command line codes of lifting drafts for different blocks.Users could view and modify the drafts by running the codes in Tribon system.The application proved that the reasonable and reliable lifting scheme was generated by automated design system and the efficiency of designers was also improved.
