Efficient Mechanical Analysis Method of Locking C-ring of Subsea X-tree Tubing Hanger
In order to effectively solve the problem of difficult convergence and slow speed of calcu-lation caused by nonlinearity and large deformation nonlinearity of contact between C-type lock ring and its driving components when the underwater oil production tree and the tubing hanger are locked,A method of finite element analysis was proposed by directly loading radial displace-ment on the C-ring instead of loading the traditional drive components,and combining it with the derivation of the mechanical relationship with the drive components to obtain the results of the mechanical analysis of the C-ring.A theoretical mathematical model of C-type locking ring under radial displacement loading was established,and the correctness of the theoretical model was veri-fied by finite element analysis.Combined with the practical application model,it is verified that the mechanical analysis method can effectively improve the convergence speed of finite element analysis,which has strong feasibility and high efficiency,and has important reference significance for the analysis of mechanical properties of similar components.
