摘要
采用虚拟干涉检查方式对船舶加换装对象进行三维动态预演,提前发现加换装过程中可能出现的设备更换空间不够、被阻挡等干涉情况。由于船舶生产设计整船模型量大、面片多,常用的干涉算法运行效率低。为了提高加换装动态干涉检测效率,并考虑碰撞准确性和严谨性,提出基于轴对齐包围盒-有向包围盒(Axis-Aligned Bounding Box-Oriented Bounding Box,AABB-OBB)的混合层次包围盒算法对虚拟对象进行动态碰撞检测。经验证,该方式能够在复杂虚拟环境中快速进行碰撞检查,并生成碰撞干涉结果供生产设计人员对加换装设备周边船体结构进行优化,及时精准规避可能存在的干涉问题。
A virtual interference inspection method is used to perform a three-dimensional dynamic simulation of ship retrofitting objects,in order to detect possible interference situations such as insufficient equipment replacement space and obstruction during the addition and replacement process in advance.Due to the large number of ship models and numerous surface patches in ship production design,the commonly used interference algorithms are of low operational efficiency.In order to improve the efficiency of dynamic interference detection for addition and replacement process,and considering collision accuracy and rigor,a hybrid hierarchical bounding box algorithm based on Axis-Aligned Bounding Box-Oriented Bounding Box(AABB-OBB)is proposed for dynamic collision detection of the virtual objects.After verification,this method can quickly perform collision detection in complex virtual environments and generate interference results for production designers to optimize the surrounding ship structure of the addition and replacement equipment,timely and accurately avoiding possible interference problems.
