摘要

针对重大件整机海运风险大、工况复杂的特点,总结了进行重大件海洋运输船舶配载的要点;探索了一套重大件整机海运结构仿真分析的方法;给出了岸桥整机结构的模块化、参数化建模的途径,大幅度地降低了仿真建模的时间。特殊节点的处理、密度的分部件赋值方法,提高了仿真计算结果的可靠性;箱梁结构的截面参数化处理为结构建模节省了大量时间。从环境荷载到海绑结构件的设计优化,形成了一套整机海运结构仿真分析体系,保证了仿真分析结果的可信度和准确性。
        In view of the characteristics of high risk and complex working conditions of large-scale and whole crane marine transportation, the main points of stowage of large-scale marine transportation ships are summarized. A set of methods for structural simulation analysis of such projects is explored. The way of modularization and parametric modeling of quayside crane structure is given, which greatly reduces the time of simulation modeling. The processing of special nodes and the method of assigning density to parts improve the reliability of simulation results. The parameterized treatment of box girder section structure saves a lot of time for structural modeling. From the environmental load to the design and optimization of sea-fasting structural parts, the simulation analysis system of the whole marine structure is formed, which ensures the reliability credibility and accuracy of the simulation analysis results.
