    摘要:

    针对卡爪式水下连接器工作环境十分恶劣、外界干扰因素较多、会受到拉、压、弯、扭等外力的作用的问题,建立了连接器的模型,对各种受力状态进行了分析,提出了连接器在各种状态下的最大承载能力的计算方法。连接器对拉力的承载能力通过确定卡爪的危险截面及伸长量进行分析;连接器对压力的承载能力取决于两法兰之间的预留距离,通过计算卡爪的最大压缩量进行分析;连接器对弯矩的承载能力以距法兰中线最远的卡爪受力为准,根据倾覆力矩对连接器进行弯矩分析;连接器对扭矩的承载能力是由连接器内部卡爪与法兰之间的摩擦力决定的,在不同工况下,根据卡爪对法兰的正压力的变化,可以得到不同的结果。通过对卡爪式连接器的受力状态分析得到的连接器承载能力,对于国内类似水下机械式连接器的发展有一个很好的借鉴作用。

    Abstract:

    or the bad working environment of the subsea collect connectors, lots of external interference factors and being subject to tension, compression, bending, twisting or other external forces, the model of connector has been built. Various stress states were analyzed, and method of calculating maximum bearing capacity was proposed under all the states of connectors. The bearing capacity of tension of the connector was analyzed by the determination of dangerous cross section and elongation of the collect. The bearing capacity of compression was depended on the reserved distance of two flanges, and was analyzed by calculating the largest amount of compression of the collect. The bearing capacity of bending moment was pivoted to the force of the collect which was furthest from the center line of flange, and was analyzed according to the theory of overturning moment. The bearing capacity of torque was depended on the friction force between flange and collect, and it was different in different working conditions according to the change of the normal force that from collect to flange. The method of analysis of bearing capacity by analyzing the stress state of connector is a good reference for development of domestic similar subsea mechanical connectors.
