摘　　要：借助有限元软件ANSYS探讨、研究了一种新型大吨位双回转铁路起重机的底架结构。在前人的基础上整体建模,把支撑油缸考虑在内,在底架与支腿传统的刚接的基础上创造型的提出了耦合的方式,更符合实际,使结果误差减小,采用底架、支腿、销轴、支撑油缸等单独建模,然后组装为一整体,在回转支承处运用APDL语言对变载荷进行加载,对支撑油缸下表面进行约束全部移动自由度和模拟地面接触两种处理办法,这样能够比较真实地反映实际工况。另外还提出了新型支腿的有限元分析,为新型大吨位双回转铁路起重机的底架结构的研究提供了参考。It discusses of finite element software ANSYS to research a new large tonnage double rotary railway crane’s base plate structure.On the basis of former overall modeling,considering the support cylinder,it proposed the coupling way creatively on the basis of the rigid connection of chassis and landing leg,which is more actual,to make the result error decrease,and it uses chassis,legs,pin shaft,support cylinder respectively to do the modeling,and then assembles them as a whole,and does the loading to variable load in rotary bearings by APDL language,and carries on two kinds of processing methods as to restrict all mobile freedom under support cylinder surface and simulate ground contact,so that it can reflect the actual working condition.In addition it also puts forward a new leg finite element analysis,providing reference for the research of new large tonnage double rotary railway crane’s base plate structure.
