摘要
本文基于有限元方法,采用总体桁架梁单元模型和缆索单元联合的分析方法,对某型全海深ARV起吊工况下框架结构强度、稳定性和刚度进行分析,并依据规范进行校核和优化,最后进行框架极限承载试验验证。结果表明:框架经受了极限承载试验的考核,框架设计合理;试验结果与计算结果接近,说明本文建立的框架结构计算分析方法,可为全海深ARV框架的结构计算和优化设计提供参考。
In this paper,based on the finite element method,an overall truss beam element model and the ca⁃ble element combined analysis method were used to analyze the strength,stability and stiffness of the frame⁃work of a certain full-ocean depth ARV under the lifting condition,which was checked and optimized accord⁃ing to the specifications.The analysis results were verified by the ultimate bearing test of the framework.The results show that the framework has withstood the ultimate load test,and that the framework design is reason⁃able.The experimental results are close to the simulation results,which indicates that the method established in this paper can serve as a reference for the structural calculation and optimization design of full-ocean depth ARV frameworks.
