Modular Design and Finite Element Analysis of Agricultural UAV

摘要: 近年来，随着信息技术的不断进步，使得无人化农业成为可能，其中农业无人机产业呈现良好发展前景。本文利用Solidworks模块化设计了一种农业无人机模型，克服了传统四旋翼无人机零配件拆装困难等问题，在材料的选择上兼顾重量和承载力，在受力零件采用了7050铝合金和合金钢，轻量化的同时提升了整体的力学性能，然后导入到Ansys Workbench软件，对无人机中重要零件进行静力学分析，对结构进行分析验证合理性，最后在不同工作条件下的仿真实验条件下，确定了无人机模型。

Abstract: In recent years, with the continuous progress of information technology, unmanned agriculture has become possible, among which the agricultural drone industry shows good prospects for develop-ment. In this paper, an agricultural UAV model is designed using Solidworks modularization, over-coming the problems of traditional quadrotor UAV parts disassembly and assembly difficulties, taking into account the weight and load-bearing capacity in the selection of materials, using 7050 aluminum alloy and alloy steel in the stressed parts, which improves the overall mechanical prop-erties while lightweight, and then imported into Ansys Workbench software to The important parts in the UAV are analyzed statically, the structure is analyzed to verify the rationality, and finally, the UAV model is determined under the simulation experimental conditions of different working condi-tions.
