摘要
本次设计首先通过分析现有伸缩臂式叉装车的结构与功能，类比一台伸缩臂叉车，设计出一个物流叉车的伸缩臂。然后对伸缩臂进行受力分析和应力校核，检验设计合理性。接着在Pro/E5.0软件中，对伸缩臂进行建模，对每一节臂进行有限元分析，分析每级臂的应力大小和应力分布，对伸缩臂进行结构优化。最终对伸缩臂进行运动仿真，分析伸缩臂的运动情况，检验伸缩臂的运动情况。本设计主要是针对小型电动物流叉装车，设计其臂架系统，最终结合组内其他同学的设计，完成整个小型电动物流叉装车的设计。
本文最终设计出一个全伸状态为10m，全缩状态为4.5m的截面形状为六边形，厚度为6mm的三节伸缩臂，经过受力分析，应力校核，有限元分析和结构改进，最终结果表明设计合格，可以达到设计要求。

Abstract
Firstly, by analyzing the structure and function of the existing telescopic forklifttruck, this design analogizes a telescopic forklift truck, and designs a telescopic arm of logistics forklift truck. Then the force analysis and stress checking of the telescopic arm are carried out to verify the rationality of the design. Then, in Pro/E5.0 software, the telescopic arm is modeled, the finite element analysis of each arm is carried out, the stress magnitude and distribution of each arm are analyzed, and the structure of the telescopic arm is optimized. Finally, the motion of the telescopic arm is simulated, the motion of the telescopic arm is analyzed, and the motion of the telescopic arm is checked. This design is mainly aimed at small electric logistics forklift truck,designed its boom system, and finally combined with the design of other students in the group, completed the design of the whole small electric logistics forklift truck.
In this paper, a three-section telescopic boom with a full-extension state of 10m, a full-shrinkage state of 4.5m and a thickness of 6mm is designed. After stress analysis, stress checking, finite element analysis and structural improvement, the final results show that the design is qualified and can meet the design requirements.
