基于NX nastran新型显示屏支架的有限元分析

Finite element analysis Of a new type Display Screen Bracket Based on NX nastran

针对军用工程机械用的新型显示屏支架的结构特点,提出一种集成Solidworks和NX nasran软件系统对军用工程机械用的新显示屏支架结构进行有限元建模的静力学分析和模态分析的方法,通过分析计算得到在满载工况下的变形情况和应力分布情况,以及支架结构前8阶的固有频率和振型图,找出其振动的危险区域,为军用工程机械用的新显示屏支架的优化设计提供一种分析评价的依据。

According to the characteristics of military construction machinery with new display screen bracket structure proposed new screen bracket structure of an integrated in SolidWorks and Nx nasran software system of military engineering machinery with the finite element modeling of the static analysis and modal analysis method,through analysis and calculation obtained under full load conditions of deformation and stress distribution,and the support structure of 8th Order inherent frequency and vibration type figure,find out the dangerous area of the vibration,provide a basis to analysis and evaluation of new screen support for military construction machinery optimization design,
