我厂船体车间室内制造的船体分段,由于外形尺寸大、分量重,而车间室内又只有一部30吨桥式行车,因此,当要进行分段翻身焊接时,过去的办法是,将所要翻身的分段,先从胎架上驳运到一辆简易的40吨橡皮轮胎平板车,由大功率汽车头,把分段拖到船台高架吊车附近,用两座高架吊车将分段在空中翻好身,再拖回到车间内进行焊接。 相似文献

[Objective]To simplify the ship modeling process and improve modeling efficiency, this paper proposes a method for rapidly implementing hull model creation based on hull line drawing.[Methods]Using the CATIA platform, this method adopts the component application architecture (CAA) development tool for secondary development. First, by reading the geometry elements and label information of the hull lines in a drawing, the transformation of the offset points from 2D to 3D is realized. On this basis, the creation of the hull lines, stern and bow is completed, and a 3D wireframe model obtained. Finally, the hull 3D modeling is completed in conjunction with the CATIA native surface creation command. The stability and reliability verification of the developed type value extraction and bow generation program is then carried out via application analysis.[Results]The results show that the compiled program can realize the automatic creation of offset points, transverse lines, waterlines, profile lines and other boundary lines except the top line of the wall, and the centerline and tangent lines created by the bow generator are easily modified and simple for users to operate. [Conclusions]The verification results show that the method of a creating hull model using "Generative Shape Design" and "Drafting" with the hull line drawing as the data input is stable, reliable and able to realize rapid hull modeling, giving it certain practical value. © The Author(s) 2022. 相似文献

自主式水下航行器的耐压和密封是非常关键的两方面,基于SolidWorks软件对324型AUV耐压舱体进行了设计与仿真校核。综合考虑薄膜理论和不连续效应,根据NSGA-Ⅱ算法实现多目标优化,确定出直舱和封头的基本尺寸,利用美国海军试验水槽公式和稳定条件进行初步验证,以保证强度和稳定性。根据得出的几何尺寸在SolidWorks里完成三维建模,并在Simulation模块中完成数值模拟仿真,最终对舱体进行实际耐压试验,将结果和理论计算、软件仿真进行对比。针对直舱段舱体不同尺寸和材料进行了三维建模和数值仿真,得出相应结论。 相似文献
