摘　　要：主要研究大型港机结构安全控制数据的可视化问题.在了解数据集中的数据结构和数据类型的基础上,选择适当的可视化工具,将大型港机结构中的单个测点和多个测点的应力数据以及与安全管理相关的参数和变量,通过多种二维图形展示给设备管理人员,从而提升其对设备的了解和洞察力.同时,通过对结构损伤的分析,为创建疲劳裂纹萌生寿命估计和疲劳裂纹扩展寿命预测的数据挖掘模型奠定基础.This paper is concern about the visualization of the safety control of large port machine structure. On the basis of well understanding of the structures and types of the data,we chose the suitable data visualiza- tion(DV)tools to show the stress of one single point or several points of the selected port machine as well as those variables and parameters which are relative to the structure safety administration.These data were shown to the equipment administrator with two-dimension charts,helping them get a better understanding and insight of the equipments.Meanwhile,by means of analysis of the structure damnification,we lay a solid foundation for the establishment of the data mining model for estimation and classification of the flaw sprout life and data mining model for prediction of the flaw extension life.
