基于 ABAQUS／Explicit 的深水连接器准静态分析

摘要

介绍了深水套筒式连接器的结构与工作原理。建立了有限元模型，运用 Abaqus/Explicit 显式准静态分析求解，从能量的角度判定模型分析的准确性，从计算结果判定该连接器的设计能否满足强度要求。显式准静态分析求解既保证了数值计算的准确性，又解决了静态分析复杂接触时严重的不收敛问题，为解决复杂接触的静力问题提供了一种方法。%The structure and working principle of deepwater collet connector is introduced.Finite element model is established,Abaqus/Explicit quasi-static analysis is used to solve the model,the accuracy of the model analysis from an energy point is determined and the design of the connector is determined if it can meet the strength requirements or not on the basis of calculation results. Quasi-static analysis could not only ensure the accuracy of numerical computation,but also solve serious non convergence problem of static analysis of complex contact,and provide a way to solve static problem of complex contact.
