摘　　要：有限元法是一种求解偏微分方程边值问题近似解的数值计算方法,因其原理简单、求解能力强等优点,在静力学分析、动力学分析、热传导等领域得到了广泛的应用,在处理复杂的非线性边界条件时具有明显优势,通过有限元分析软件,对上料装置进行静力学分析,通过对有限元分析得到的结果进行分析,找出装置应力集中及变形量较大的位置,并对不合理的位置进行结构优化,从而实现对结构的优化,保证上料装置的力学性能及结构的合理,减少实际试错成本。The finite element method is a numerical calculation method for solving approximate solutions to boundary value problems of partial differential equations.Due to its simple principle and strong problem-solving ability,it has been widely applied in fields such as static analysis,dynamic analysis,and heat conduction.It has obvious advantages in dealing with complex nonlinear boundary conditions.This article uses finite element analysis software to conduct static analysis of the feeding device,by analyzing the results obtained from finite element analysis,identify the locations with high stress concentration and deformation in the device,and optimize the structure for unreasonable locations to achieve structural optimization,ensure the mechanical performance and structural rationality of the feeding device,and reduce actual trial and error costs.
