Optimization and Experimental Study of the Subsea Retractable Connector Rubber Packer Based on Mooney-Rivlin Constitutive Model

The sealing performance of the rubber packer is vital importance for subsea retractable connector, and cross-sectional shape one most important factors affecting it. compression distance increased by 19.54% utilizing established two-dimensional numerical model. In addition, a new parameter called anti-shoulder extrusion variable was defined in this paper. Shoulder will not occur when using as constraint during simulation. general, upper end lower are subject to different constraints, structural parameters affect each other terms performance. Therefore, originality study exploring optimization thickness chamfer angles ends use combination response surface method multi-objective genetic algorithm, taking design variables, stress on inner side casing wall axial force compressed objectives. Besides that, variables also introduced constraints prevent shoulder extrusion. Ultimately, with smaller-thickness larger-angle end, larger-thickness smaller-angle can be obtained. result emerge from test paper that pipe pressure sealed optimized structure 25.61% higher than before optimization. asymmetric proposed shed light finite element simulation research similar seals.
