摘　　要：为了实现船体外板展开的自动化以及对展开精度的控制,在手工撑线法展开船体外板的理论基础上,提出一种三维船体曲面外板展开的新方法——小曲面三角形法。介绍三角形法展开船体外板的机理,理论分析三角形法展开船体外板的可靠性与精度,利用TRIBON软件产生的外板数据,对其进行三角形法展开,将得到的结果与TRIBON生成的船体外板展开图进行对比,验证三角形法的可靠性与精度。To realize the automatic shell expansion by computer and control the accuracy of expansion, a new method of the expansion of 3-D curvature hull plate, small curve triangle method was put forward basing on the theory of propping line method. The mechanism of shell expansion using small curve triangle method was elaborated, and its reliability and accuracy was analyzed. The shell expansion results using the proposed method were compared with the generated unfolded drawing from TRIBON, verifying the reliability and accuracy of the small curve triangle method.
