摘要/Abstract

摘要： 船舶构件制造和装配中的制造误差与装焊变形影响肋板拉入装配的成功率和效率。提出了基于几何特征的船舶大尺寸构件快速建模及装配干涉检测方法。该方法先定义装配特征，再利用改进的ASPacNet准确识别装配特征，接着进行局部重建与拼接，最后通过时间域间断配合间隙计算方法检测装配干涉。实验显示，该方法在船舶大尺寸构件上的建模效率较传统方法提高66.01%，建模均方根误差为0.206 mm，干涉检测准确率达98.81%，能有效减少试装，为船舶大构件高效装配提供新技术手段。

Abstract: Manufacturing errors and welding deformations in manufacturing and assembly of ship components affected the success rate and efficiency of rib plate pulling-in assembly. Therefore, a rapid modeling and assembly interference detection method for large ship components was proposed based on geometric features. The method defined assembly features, used the improved ASPacNet to accurately identify the assembly features, carried local reconstruction and splicing out, and detected assembly interference through a time-domain intermittent fit clearance calculation method. Experiments show that the modeling efficiency of the method for large ship components is 66.01% higher than that of traditional methods, the root mean square error of modeling is as 0.206 mm, and the interference detection accuracy reaches 98.81%. It may effectively reduce trial assembly and provide a new technical means for the efficient assembly of large ship components.

Key words: , assembly feature recognition, rapid modeling, large-scale components of ship, rib pull-in assembly, precision detection
