Abstract
The elastic mechanism is applied in offshore completion sand control tubular column tools,with its mechanical deformation mechanism exerting significant influence on the effective service life and operational reliability.This study investigates the deformation mechanism and structural optimization of the elastic claw mechanism in load indicators through a combination of finite element simulation and mechanical property experiments on the elastic claw.Findings demonstrate that the initial stage of elastic claw deformation is dominated by local plastic deformation and cold work hardening.Through comparative cyclic loading experiments of elastic force for 42 CrMo and 60 Si2Mn materials,it is revealed that under identical working conditions,the service life cycles of the elastic claw fabricated from 60 Si2Mn material exceed those of 42 CrMo.Further orthogonal optimization design for 60 Si2Mn material yields the optimal structure:short slot radius of 7.0 mm,short slot center distance of 127.0 mm,long slot radius of 3.5 mm,and long slot center distance of 199.0 mm.Under this configuration,the load for the elastic claw to pass through the coupling is approximately 1.995 t.Notably,adjusting the short slot radius while maintaining elastic claw stiffness can reduce the required load for the coupling to traverse the elastic claw.关键词
