| 摘 要： | 无人引导小车（AGV）是一种新型的移动机器人，广泛应用在各个领域中。针对复杂路况下专用的AGV运输小车的设计，本文所研究的AGV运输小车是由底盘、行走机构、举升装置和可拆卸器件等组成。通过对AGV运输小车的机械结构进行设计与分析，并结合静力学理论讨论本文设计的小车结构可行性。利用Solid Works软件对AGV运输小车进行三维模型建模，并对小车的行走机构进行静力学分析，将小车的三维模型通过Solid Works Smiulation进行应力分析，得到小车在负载状态下轮系结构的受力和变形情况云图，通过AGV运输小车在各种工况下的变形云图验证轮系结构的合理性，并基于变密度法拓扑数学模型优化对小车车体框架进行优化设计，节省车体材料的使用。依照TRIZ理论的4个通用工程参数获得履带张紧结构和车架的设计。最后利用分割，改变颜色，维数变化等原理进行智能AGV运输的造型设计，以期为AGV运输起重装置方便货物的起降装卸，改变了人力操作机器的传统搬运模式。 |

| Abstract: | Unmanned Guided Vehicle (AGV) is a new type of mobile robot that was applied in various fields. Aiming at the design of dedicated AGV transport vehicle for complex road conditions, this AGV transport vehicle is composed of chassis, traveling mechanism, lifting device, and removable components. By designing and analyzing the mechanical structure of the AGV transport vehicle, and it’s combined with statics theory, and the feasibility of the trolley structure is designed and discussed. The three-dimensional model of AGV transport vehicle is established by Solid Works software, and the cloud diagram of the stress and deformation of the wheel system structure is analyzed by Solid Works Smillation, and the traveling mechanism of the trolley is analyzed by statics. The rationality of the wheel system structure is verified by the deformation cloud diagram of the AGV transport vehicle under various working conditions. Based on the mathematical model optimization of variable density method, the car body frame is optimized and designed to these materials of car body. The design of the track tensioning structure and frame is obtained according to the four general engineering parameters of TRIZ theory. Finally, the modeling design of intelligent AGV transportation car is carried out by using the principles such as division, color change, and dimension change, etc. In order to facilitate the take-off and landing loading and unloading of goods for AGV transportation lifting device, and it is changed to the traditional handling mode of manpower-operated machines. |
