【摘要】：目前,海洋石油天然气开发已成为世界石油工业的热点和科技创新的前沿,海洋铺管船的研制是海洋石油工业发展中的重大关键设备。铺管船张紧器作为海洋铺管船的核心设备,其行为直接影响整个海洋铺管作业。因此,研究铺管船张紧器在真实工况下的受力状态并进行分析,对其改进和优化设计有较大的工程价值。研究铺管船张紧器工作时的动态性能和管道在被夹持过程中的受力情况,分析了压载器张紧轮端振动原因并提出抑振方法。提出采用数字样机仿真分析与实物样机测试相结合的研究办法,分别在ADAMS与ANSYS中建立了张紧器整机多体动力学模型和压载器-管道局部有限元模型,根据张紧器实际工况,对上述数字样机进行数值仿真。实物张紧器采用现场测试的方法,获得了张紧器管道受力与振动状况。通过仿真结果与测试结果的比较,验证了数字样机的正确性与有效性。并通过张紧器的数字样机虚拟试验,探讨了张紧器压载器张紧轮端振动的抑制方法。该数字样机能够有效地分析与研究张紧器的动静态性能,有助于张紧器的设计与改进工作,对铺管船研制具有重要应用意义。
[Abstract]:At present, the exploitation of offshore oil and natural gas has become a hot spot in the world oil industry and the frontier of scientific and technological innovation. The development of offshore pipeline laying ship is a key equipment in the development of offshore oil industry. As the core equipment of the pipeline laying vessel, the behavior of the tensioner directly affects the whole ocean pipe laying operation. Therefore, it is of great engineering value to study and analyze the stress state of the tensioner under the real working condition, and to improve and optimize the design of the tensioner. The dynamic performance of the tensioner and the stress on the pipe during clamping are studied. The causes of the vibration at the end of the tensioning wheel of the ballast are analyzed and the vibration suppression method is put forward. The research method of combining digital prototype simulation analysis with physical prototype test is put forward. The multibody dynamic model of tensioner and the local finite element model of ballast pipeline are established in ADAMS and ANSYS respectively. According to the actual working conditions of tensioner, the dynamic model of the tensioner and the local finite element model of the ballast pipe are established. The numerical simulation of the above digital prototype is carried out. The stress and vibration of the tensioner pipe are obtained by field test. The correctness and validity of the digital prototype are verified by comparing the simulation results with the test results. Based on the virtual test of the tensioner, the method of suppressing the vibration at the end of the tensioner ballast is discussed. The digital prototype can effectively analyze and study the dynamic and static performance of the tensioner, which is helpful to the design and improvement of the tensioner, and has an important application significance for the development of the tube-laying ship.
