摘　　要：基于数值有限元软件Ansys,对丹江口大坝加高工程布料机进行了有限元建模研究,并对布料机有限元模型进行了模态分析,计算得到了前六阶模态下固有频率和振型,为布料机结构其他动态分析打下了基础,为进一步的结构设计和改造提供了理论依据。Based on numerical finite element software Ansys,the finite element modeling research is done on spreader for the Danjiangkou dam heightening project,modal analysis is performed for finite element model of the spreader,and natural frequencies and modes of vibration for the first 6-order modals are figured out.The above results provide basis for other dynamic analysis of spreader structure,as well as theoretical basis for further structural design and improvement.
