摘要:

为解决水下石油管道法兰连接机具20个螺栓同时引入螺母的难题,根据水下管道法兰连接机具作业需求,设计了螺栓引入装置,通过设置弹簧、尼龙导向套和橡胶支撑环,保证螺栓可靠地引入螺母。针对水下作业环境,建立了螺栓引入螺母碰撞过程的数学模型。运用ADAMS动力学仿真软件,建立螺栓引入装置系统多体动力学模型,并对其作业过程进行动力学仿真,得到了螺栓引入螺母过程的速度、位移曲线,为机具的实际作业运动控制提供依据。碰撞过程的仿真结果表明,单组螺栓与螺母的碰撞力为173.9N,弹簧最大压缩量为5.1mm,满足系统设计要求。在螺栓引入装置试验样机上进行螺栓引入试验,结果表明螺栓能成功引入螺母,验证了螺栓引入装置结构设计的合理性。

Abstract:

To solve the problem of 20 bolts synchronous lead-in nuts for underwater petroleum pipeline flange connection tool,a bolt lead-in device was designed according to the operational requirements of underwater pipeline flange connection tool. By setting the spring, nylon jacket and rubber support ring, bolt can be reliablly lead-in the nut. For the underwater environment, the mathematical model of collision that the bolt lead-in the nut was set up. The multi-body dynamics model of bolt lead-in device system was built by ADAMS, and the speed and displacement curve of nut was gained by the study of its operating process dynamics simulation. The results provide basis for actual motion control. Through the collision simulation analysis, bolt and nut impact force curves and the spring deformation curves were obtained. The experiment of bolt lead-in device test prototype was carried on. The experimental results show that the bolt can lead-in the nut successfully, and verify the reasonableness of bolt lead-in device mechanism design.
