7500t/h装船机总体设计及内臂架结构设计(含CAD图)(任务书,开题报告,外文翻译,论文说明书17000字,CAD图4张)
摘要
本次毕设以起重机专业知识为基础，对7500t/h装船机进行了整体设计和内臂架结构的设计。首先对装船机的整机进行设计，其中包括了工作级别，各机构大致尺寸和重量。然后计算出各种载荷以及载荷组合，完成了对轮压和抗倾覆稳定性进行了校核计算，其结果满足设计要求。用Workbench对模型有限元分析，判断结构的强度和稳定性是否符合要求。
本文以7500t/h装船机为研究对象，在整体设计时，参考起重机设计手册，对装船机进行了类比，其结果也满足设计要求。同时，在内臂架设计过程中，参考传统的设计方法，利用计算机辅助设计软件和有限元分析软件，求得了内臂架在受载时的应力云图和应变云图，大大节省了设计时间，也为以后的内臂架结构优化设计提供了理论基础。

ABSTRACT
Based on the professional knowledge of the crane, the overall design and the inner boom structure design for the 7500t/h ship loader were completed in the graduation design.First of all,the overall design includes the working level,the approximate size and weight of each mechanism.Then various load and load combinations were calculated,and check the wheel pressure and anti-overturning stability,the results met the design requirements. import it into workbench for finite element analysis,determine whether the strength and stability of the structure meet the requirements.

This article takes the 7500t/h ship loader as the research object. In the overall design, the crane design manual is referenced and the ship loader is compared. The results also meet the design requirements. At the same time, in the design process of the inner boom structure, with reference to the traditional design method, the computer-aided design software and finite element analysis software were used to obtain the stress cloud map and strain cloud diagram when the inner boom structure was loaded, which greatly saved the design time. It provides a theoretical basis for the future optimization design of the inner boom structure.
