基于知识工程的船舶机舱设备三维布局设计

Design of Three-Dimensional Layout of Ship Engine Room Equipment Based on Knowledge Based Engineering

船舶机舱设备布局设计属于密闭有限空间多目标优化设计问题,作为船舶的心脏,机舱设备的布局效果会影响到整条船舶各方面的性能.通过CATIA软件和知识工程技术对一艘多用途载货船舶机舱设备进行三维布局设计研究,建立船舶机舱分类规则以提高知识获取效率;建立设备虚拟面积增加规则来控制设备间距;运用参数化装配完成知识推理.最后,对生成的布局方案通过横倾力矩、干涉检查及逃生时间3项规则进行专家校验,结果符合预期,验证了知识工程在船舶机舱三维布局设计中的可行性和有效性.

The layout design of ship engine room equipment belongs to the multi-objective optimization design problem of confined limited space.As the heart of the ship,the layout of engine room equipment will affect the performance of all aspects of the entire ship.By using CATIA software and knowledge based engineering module,the 3D layout design of the engine room of a multi-purpose cargo ship was studied.Ship engine room classification rules were established to improve the efficiency of knowledge acquisition,equipment virtual area increase rules were established to control equipment spacing,and parameterized assembly were used to complete knowledge reasoning.Finally,the generated layout scheme was verified by experts through three rules of roll torque,interference inspection,and escape time.The results are in line with expectations,and the feasibility and effectiveness of knowledge based engineering in the 3D layout design of ship engine room are verified.
