EXPERIMENT STUDY ON THE STINGER ROLLER LOAD

The stinger roller load is the main force during the analysis of the pipeline and the design of the stinger, but it is difficult to get the exact results through the regular calculation or experiment methods because of the nonlinear and random factors. The study on the roller load based on the hard-in-the-loop simulation experiment is carried out at the State Key Laboratory of Structural Analysis for Industrial Equipment. The roller load is directly measured by this system. The static force comparison between experiment and calculated one is made, and the results agree well with the calculated one. The dynamic reaction force between a stinger and a pipe may cause the fatigue and the increase of the stress of ship structures.
