摘要
以55tU型双梁门式起重机为例,详细描述了对具有铰接式柔性支腿大跨度门式起重机整机金属结构进行有限元分析过程中的建模、约束、加载等步骤的合理处理,并对计算结果进行分析,提出了对实际工程设计具有参考意义的建议。
Using the model 55 t U-shaped double-girder gantry crane as an example, this essay elaborates on the proper handling of various steps involved in a finite element analysis of the overall metal structure of a large-span gantry crane with hinged flexible outriggers, including modeling, constraining, loading, etc. , analyzes the calculation result a- chieved, and then puts forward suggestions of values as reference to practical engineering design.
