摘　　要：对船舶模型进行局部结构有限元分析时,添加载荷有时只是针对船舶有限元模型的舱壁、舷侧、内外底和甲板上的有限元网格。从模型中划分出这些部位上的网格单元,目前的方法还只限于从模型中手工提取,操作繁琐,耗时较长,效率低且易出错。以MSC.Patran为处理平台,使用PCL语言,开发出3D舱室边界单元自动识别系统。结果表明,该自动识别系统的开发,能够准确的识别出舱室的边界网格单元,进而大大提高工程技术人员的分析效率。In the partial structural analysis of ship FEM model, adding load sometimes aimed at mesh of model＇s bulkhead, shipboard and deck. The present method of extracting requisite elements from model is only by hand, which is tedious, time-consuming, inefficient and fallible. With MSC. Patran as a pre-processing and post-processing platform, AIS （automatism identification system） of 3D cabin boundary element is developed by using PCL language. The result shows that the AIS can accurately identify boundary elements of cabin, resulting in enhancing analytical efficiency.
