伸缩臂叉装车总体结构设计

摘要：伸缩臂叉装车已成为高空作业设备的重要门类，是广泛应用于建筑工地、工矿企业仓库和其他工地上起升、运输、堆放砖头、木材、钢材和其他物料的一种起重运输设备，随着经济建设的发展，对其需求越来越大，对其性能的要求也越来越高。本文主要任务是完成对 伸缩臂叉装车的总体计算、整体布局、臂架结构设计及其有限元分析。 本文主要内容：

⑴ 介绍伸缩臂叉装车的用途、国内外伸缩臂叉装车发展状况的比较、及其发展前景。同时对臂架的结构和工作原理做了简要介绍。

⑵ 完成对关键铰点的布置，作业高度、作业幅度的计算，及整机稳定性的校核计算。并绘制出整机总体布局图。

⑶ 臂架的结构设计，臂架的强度、刚度和稳定性计算，并用ANSYS软件进行臂架有限元分析。同时完成臂架系统装配图，一节臂、二节臂的装配图和相关零部件的工程图。

⑷ 设计过程采用Pro/E软件进行三维实体建模，并进行装配，最后应用其工程图模块转化为二维工程图。

本次设计的 伸缩臂叉装车参考了JCB公司的JCB530型号伸缩臂叉装车的外形尺寸，并且严格按照《起重机金属结构》、《BS_EN_1459-1999》和《机械设计手册》等相关设计规范进行设计，其性能和质量满足相关要求。

The Frame Structure Design of Telehandler

Abstract： Telehandler is a kind of hoisting equipment which is widely used in building site、

storage and other place to lift、transport、stack the tile 、wood 、steel products and other materiel . Along with the development of economic in our country, the requirement of crawler crane is larger and larger, and the request of the capability is higher and higher.the mission of this paper is to complete the frame structure design of telehandler、the design of boom structure and the finite analysis of boom.

The primary contents in this paper can be concluded as follows:

The use of the telehandler、the telehandler’s development comparison domestic with abroad、and the development trend of the telehandler are introduced.At the same time,the paper introduces the structure of boom and how boom works, and gives the principle of how to choose the boom.

The pivot points arrangment , the calculation of lift height and forward reach, and the calculation of the stability are completed.The integral layout drawing is provided.

The structure design of the boom, the calculation of the strength and stability of the boom system are accomplished and the finite analys of boom is achieved by ANSYS software. While at the same time planar engineering drawing must be done, such as the assembling of the boom system, the boom one the boom two and the related parts.

I use the Pro-E software to design the 3D entity, and make dummy assembly. And then, the 3D entity is transformed to the planar engineering drawing with the Pro/E planar engineering drawing module.

In the design process, I refer to the JCB530 telehandler of JCB, and accord to the《Crane Metal Stuctrure》、《BS_EN_1459-1999》and the《Machine Design Handbook》strictly. Its capability and quality meet the requirement.
