| 摘 要： | 建立船舶操纵运动数学模型,计算确定相邻的岸线线段和船舶轮廓线线段之间的凹凸关系,提出船舶操纵运动仿真中船舶碰岸检测算法,并对检测到的碰岸情况进行时间步长调整。编制了计算程序,对于船舶轮廓线端点位于岸线内侧和岸线端点位于船舶内部两种船舶碰岸情况进行了碰岸检测仿真试验,试验结果良好,很好地避免了在船舶操纵运动仿真中出现船舶冲上码头或者岸滩的现象。

| Abstract: | The mathematical model for ship maneuvering motion is established. The relation of concave or convex between neighborhood lines of shoreline and ship contour is calculated. The method for check of collision between ship and shoreline for ship maneuvering motion simulation is presented. The time step is adjusted, if collision between ship and shoreline happens. The program of calculation is worked out and simulation tests on check of collisions for the point of ship contour inside shoreline and the point of shoreline inside ship contour are carried out, and its results are very good. The phenomenon of ship on dock or shore is avoided for ship maneuvering motion simulation. |
