摘要:

 以某公司初步设计的一款30 MN三梁四柱式双动拉伸液压机为研究对象,此液压机为一款新型液压机。采用有限元方法对液压机整体机架进行结构分析与模态分析,获得上梁、滑块、底座及立柱4个主要部件的变形和应力情况,对液压机进行初步校核,并获得其前6阶固有频率。结果表明:上梁的最大静挠度不符合工程要求,通过对上梁结构优化,使其接近工程要求;滑块与底座的最大静挠度符合工程要求,所以在保证滑块与底座符合工程要求的基础上,进一步对滑块和底座进行轻量化设计,达到减重的目的,为最终30 MN三梁四柱式双动拉伸液压机的设计和制造提供了一定的理论参考。

 For a 30 MN three-beam and four-column double-action tensile hydraulic press initially designed by a company, it is a new hydraulic press. Therefore, the structural analysis and modal analysis on the overall frame of the hydraulic press were carried out by the finite element method to obtain the deformation and stress situations of the main components such as upper beam, slider, base and column. Then, a preliminary check on the hydraulic press was conducted, and its first six natural frequencies were obtained. The results show that the maximum static deflection of upper beam does not meet the engineering requirements, and by optimizing the structure of upper beam, it is close to the engineering requirements. However, the maximum static deflection of slider and base meet the engineering requirements, on the basis of ensuring that the slider and base meet the engineering requirements, the lightweight design of slider and base is further carried out to achieve the purpose of weight reduction, which provides a certain theoretical reference for the design and manufacture of the final 30 MN three-beam and four-column double-action tensile hydraulic press.
