EXPERIMENTAL STUDY AND NUMERICAL SIMULATION OF MECHANICAL BEHAVIOR OF TRUSS BOOM DURING HOISTING PROCESS

  • 摘要: 吊机是海洋钻井平台的关键设备,为确保整套系统的安全运行,研究桁架式吊臂在变幅平面内的结构力学性能. 考虑到桁架式吊臂的结构特点及构件性能退化等不确定因素,采用有限元方法,以承载杆件应力为修正指标考虑损伤的影响,建立了吊臂的三维数值模型,对变幅全过程进行了数值模拟和试验研究,结果表明:应用该方法可以比较真实地模拟出吊臂的变幅过程和结构力学性态,确定结构的薄弱部位,为吊装作业和吊臂结构的安全运行提供有价值的建议,适合工程应用.
    Abstract: The crane is a key equipment for an ocean drilling platform. To ensure the safe operation of the entire system, it is necessary to study the structural mechanical property of the truss boom in the hoisting plane. With consideration of such uncertain factors as the structural features of the truss boom and the component performance degradation, a three-dimensional numerical model of the boom is built using the finite element method, in which, the stresses of the main load-bearing member bars are taken as the key indicators and the relevant design parameters as the input updating objects. Numerical simulations and experiments on the whole hoisting process are carried out. It is indicated that the method can simulate the hoisting process and the structural mechanical property, the failure shape and the dangerous position can be obtained. This method provides some insight for the lifting task and the security operation of the jib structure, and is suitable for engineering applications.
