在港航工程设计论证、船舶操纵性能测试、港口航道与码头通航安全评估等模拟试验过程中，经常需要对船舶操纵产生的航迹进行叠加显示，以分析不同工况对船舶航行的影响程度，给出船舶安全航行所需的航道宽度。基于大连海事大学研发的V-DRAGON3000型船舶操纵模拟器进行二次开发，增加航迹叠加功能，可实现多次船舶操纵试验结果的同时回访，获取各工况下船舶航迹带，用于通航安全、航道宽度设计与验证等试验结果分析及研究，并通过江阴港区的泊位工程安全通航评估论证其有效性。%In port and waterway engineering design argument,the ship maneuvering performance test,the channel ports and terminal navigation safety assessment simulation test process,often used to track the overlay display,with the analysis of ship under different conditions,the degree of influence on the voyage,the ship navigation safety in order to give the required width of channel. This paper describes the V-DRAGON3000 type of Ship Handling Simulator of Dalian Maritime University has developed a two development, add an overlay function under the condition of the ship track,get the overlay graph,facilitate the analysis and study of the global,the validity of the demonstration of practical cases and by a navigation assessment.
