ANSYS16T偏挂起重机结构设计及有限元分析+CAD图纸
本文首先分析了该型起重机的工作状况和受力特点，确定了起重机总体结构参数和主梁所用材料；设计了主梁的主要组成部分和几何尺寸；通过主梁受力分析，确定了主梁截面尺寸，并进行了强度和刚度校核。
课题对起重机主梁进行了有限元分析。采用PRO/E建立了主梁的实体模型，并导入ansys软件中，选择BEAM3单元；材料属性为16Mn；自动划分网格；在梁两端施加固支约束，在梁跨中施加载荷。分析结果表明，主梁的最大应力位于跨中位置，变形为41.041mm满足设计要求。
在结构设计和有限元静力分析的基础，完成该型起重机相关装配图和主要零件图的绘制。

With the rapid development of China's economy, the use of crane is more extensive, the demand is increasing, and the safety and economy of the crane is higher and higher.Partial hanging gantry crane is a crane, also known as gantry crane.It is mainly used for outdoor yard handling operations, at the port, a widely used freight yard.This topic of 16t partial hanging crane is the research object, the modern design method, the finite element method, the girder, which is an important component of crane for structure design and finite element analysis, in order to improve the reliability and economy of the structure.
In this paper, the working status and the characteristics of the crane are firstly analyzed, and the overall structure parameters and the material of the main girder are determined.The main components and geometrical dimensions of the main girder are designed, and the main girder is determined by the stress analysis of the main girder, and the strength and stiffness are checked.
The subject of the crane girder is analyzed by finite element method.. The solid model of the main girder is built by PROE and imported into ANSYS software.The material properties are BEAM3, the material property is 16Mn, and the grid is pided automatically, and the fixed supports are applied to the beam at the ends of the beam, and the load is loaded in the middle.The results show that the maximum stress of the main girder is located in the middle position and the deformation is 41.041mm to meet the design requirements.
Based on the structural design and finite element analysis, the assembly drawings and the main parts of the crane are completed.
