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

Abstract

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.
