Research on Welding Process Modeling and Narrow Operating Area Searching for Shipbuilding Block

针对船舶分段装焊过程中极易出现分段区域空间狭小、导致工人焊接作业困难的问题,提出了结合分段装焊工艺过程仿真的狭小操作区域搜索方法。建立了基于船体分段结构模型、焊接工艺信息模型、焊接仿真资源模型为基础的分段装焊工艺仿真模型。建立了人体焊接操作姿态空间简化模型,利用碰撞干涉对焊缝焊接所需的操作空间大小进行快速检测,实现基于装配工艺顺序的分段建造潜在狭小操作区域的求解,为船舶设计方案人机工学评估提供有效输入。基于上述方法开发了原型系统,并通过实例证明了本方法的有效性。

To solve the status that the welding operation is difficult because of me narrow segmented regions in shipbuilding block, the searching algorithm of narrow operating area combined with welding process simulation model was presented. Block model of ship, welding process model and welding resource model were completed to establish the block welding process simulation model. The collision and interference detection was used to check the space required by the welding operation rapidly, and then the potential narrow operating area based on the sequence planning of assembly process was achieved. The area can provide effective input for the man-machine engineering assessment of ship design. Prototype system was developed based on the methods above, and the effectiveness of this method has been proved by an example.
