基于ANSYS的大吨位双回转铁路起重机底架的优化设计及研究

摘要

借助有限元软件ANSYS设计一种新型2880t·m双回转铁路起重机的底架结构。考虑用支撑油缸，将耦合的方式应用在底架与支腿的刚接基础上，回转支承处利用APDL语言加载变载荷，将支撑油缸下表面自由度进行约束。利用ANSYS优化理论针对底架多种危险工况下做出优化分析，对所有工况进行校核，设计出合理的双回转铁路起重机的底架结构，以解决双回转铁路起重机国产化的问题。%This paper uses the finite element software ANSYS to design a new type of 2880 t·m double rotary chassis structure for the railway crane. On the basis of the previous modeling, the support cylinder is considered to be used and the chassis is used with the leg for the rigid basis. APDL language is used in rotary bearing to change the load and constrain the degrees of freedom under the support cylinder surfaces. ANSYS optimization theory is used for the chassis in various dangers to make the optimality analysis and design the double rotary rail crane chassis structure, in order to make the national double rotary rail crane.
