摘 要

小互连子域和每个元素的合适（更简单）近似，然后导出域的总体满足条件（例如，均衡条件的结构），以获得 解决问题。这个解决方案并不是一个精确的解决方案，而是一个近似值，因为实际的问题已被一个更简单的问题所取代。因为

先在几个世纪前产生，并被应用，例如，圆的圆周由多边形（有限线性单位）近

本课题主要是研究在有限元分析软件上对外翻框架门的受力分析，然后与理论计算的结果进行比较验证有限元分析的优越性，高效性。先是在 PRO/E软件上建立外翻框架门的模型，然后使用有限元模块对已建立好的模型进行有限元分析，划分单元格，材料添加，位移约束，施加外力，模拟计算，最后得出结论。

Finite element analysis (FEA) is a mathematical approximation method for real physical system (geometry and load conditions) for simulation analysis. Or by using simple and interacting elements, ie, units, a limited number of unknowns can be used to approximate an infinite number of unknowns.

then solve. It considers the domain as a finite element, a small interconnection subdomain, and a suitable (simpler) approximation for each element, and then derives the total satisfying condition of the domain (eg, structure Of the equilibrium

The finite element is a collection of discrete elements that can be represented together in the actual continuous domain. The concept of finite element was first generated a few centuries ago and was applied, for example, the circumference of a circle is approximated by a polygon (finite linear unit) approximation. But the finite element as a method has been proposed, it is in recent years. The initial name of the finite element method is the matrix approximation method, which is used in the practical and efficient characteristics so that the research mechanics scientists after decades of efforts, the use of finite element method has rapidly expanded from structural engineering to almost all science and technology, and has become a versatile, versatile and efficient numerical analysis method.

This paper focuses on the analysis of the force of the frame frame on the finite element analysis software, and then compares the results of the theoretical calculation to verify the superiority and efficiency of the finite element analysis. Firstly, the model of the eccentric frame door is established on the PRO / E software. Then, the analysis is carried out.The elements are added, the material is added, the displacement
