摘　　要：水下连接器作为连接海底石油管道的重要部件,其强度要求十分重要,为了测试水下连接器的可靠性,研制大型连接器外载荷试验台和验证其承载能力是非常重要的。连接器试验台要能够对连接器进行拉力、压力、弯矩和扭矩测试,利用UG三维建模软件建立试验台的模型,利用有限元分析ANSYS软件得出试验台在不同极限载荷下的应力及应变分布,分析了结构的强度和刚度是否满足设计要求。研究结果表明,试验台在极限承载状态受力均在安全范围,而应变稍大,但考虑试验台尺寸很大,变形也是在可接受范围内。Subsea connector is the important connection parts of submarine oil pipelines, its strength requirement is very important. In order to test the reliability of subsea connectors, it is very necessary to develop large connector load test rig for verifying its carrying capacity. UG 3D software is used to build test rig model. ANSYS software is used to obtain stress and strain distribution of the test rig under different limit load, and analyze the reliability analysis of the impact test rig.The results show that the test rig under the state of ultimate bearing stress is in a safe range, and the deformation is a little big. Because the test bed size is large, so the deformation is in acceptable range.
