Tribon环境下船体分段拼板图自动设计方法研究

船体分段拼板图设计是船舶建造生产设计中的重要内容,目前主要依靠人工绘制,效率较低。基于Tribon的GEN文件对分段拼板图自动设计方法展开了研究,通过提取拼板图设计必需的图形信息并进行自动区域划分和定义,确定各类型数据间的相互逻辑关系。在此基础上,确定各类标注尺寸的自动计算方法,实现分段拼板图的自动设计,不仅能够提高拼板图设计的准确性,而且能够提高拼板图的设计效率。

利用TRIBON制作分段拼板图出图流程

"分段拼板图"制作的依据,是分段建模工作全部结束,即分段坡口、收缩量余量等信息建模完毕;零件号、装配计划等全部完成。这时,板架分离无误后就可以开始拼板图出图工作。拼板的大小,必须根据场地实情,如起吊能力、分段组装焊接要求来划分。拼板图便于施工人员识图,简化分段组装时流程步骤,减少现场施工组装周期。

Theoretical prediction and experimental investigation on formability of tailor-welded blanks

Based on the elastoplastic mechanical properties of the weld and heat affected zone metals obtained by a nanoindentation test, a theoretical calculation model was established for the forming limit diagram（FLD） of tailor-welded blanks（TWBs） on the basis of plastic constitutive relations and Hosford yield criteria. Hemispherical punch bulging tests were performed to verify the FLD theoretical calculation results. The results demonstrated that not only the FLD theoretical calculation of base materials but also that of TWBs had a good agreement with their experiments. Besides, poorer formability of TWBs caused its FLD significantly lower than that of base materials. The theoretical calculation model offers a reliable approach to obtain the specific FLD of TWBs.
