摘要/Abstract

摘要： 横梁结构设计的品质在很大程度上决定了动梁龙门加工中心的刚度和强度性能;横梁结构中加强筋的设计与布局直接影响横梁的静/动态特性。基于有限元法对动梁龙门加工中心的横梁进行静/动态分析,获得了横梁在极端工况下的变形情况以及横梁结构的前六阶固有频率与振型。结果表明,十字形加强筋难以满足实际工作要求,因此将加强筋结构改成米字形,使横梁的变形量减少了20.265%,一阶模态频率提高了4.405%,表明该优化设计方法合理可行,为横梁的结构设计提供了理论依据。

Abstract: The rigidity and strength performance of the moving beam longmen processing center is determined by the design of the beam structure to a great extent.The static and dynamic characteristics of the beam are directly affected by the design and layout of the reinforcing bar in the beam structure.Based on the finite element method,the static and dynamic analysis of the beam for the moving beam longmen processing center were carried out,the deformation of the beam under extreme working conditions and the first six natural frequencies and modes of the beam structure were obtained.The results showed that the cross shaped reinforcing bar can not meet the requirements of the actual work.By changing the structure of the reinforcing bar into rice-shape,the deformation of the beam was reduced by 20.265% and the first mode frequency was increased by 4.405%,which shows that the method is reasonable and feasible,can provide a theoretical basis for the design of the structure for the beam component.

Key words: longmen processing center, beam, static and dynamic, reinforcing bar
