多用途轮式电动移动平台结构设计
摘要
自动引导车（AGV）是一种经济、高效、稳定的物流运输解决方案，目前它已经从汽车工业逐渐渗透到社会的各个行业。在农业领域，AGV也已经开始试验性的应用。但是，由于现有的农用AGV大多为工业AGV的改良品，所以效果还没有达到理想状态。本次设计就是针对农业的特点，对AGV的底盘进行有目的的研发，以使其适应农田的复杂环境。同时它还能搭载各种识别、收获装置，真正实现现代化的农业生产。
设计主要采用了农用轮胎来代替以往惯用的履带和舵轮，使用四个伺服电机作为驱动和控制原动机，其中两个36W的作为转向控制电机，两个150W的作为主驱动电机。它们再配合了大传动比的减速机后，可以输出高达90N/m的转矩。这样，即使AGV行驶在高低起伏的田间，也可以“如履平地”。加强型的车身不但宽敞，而且还可以容纳更多的设备，如机械手、红外线传感器、卫星定位仪等。
这篇说明书主要阐述了AGV底盘的设计思路和原理以及设备安全度的校核。

ABSTRACT
Automatic Guided Vehicle(AGV) is an economical, efficient, stable and logistics transportation solutions, from the automotive industry has gradually penetrated into thevarious sectors of society. In the field of agriculture, the AGV has begun a pilot application. However, because most of the existing agricultural AGV for industrial AGV improved products, so the effect has notyet achieve the desired state. The design characteristics of agriculture, the AGV chassis for the purpose of research and development to adapt them to the complex environment of the farmland. It can also carry avariety of identification, harvesting device, truly modern agricultural production.
Designed primarily agricultural tires instead of the usual in the past crawler andwheel uses four servo motor drive and control the prime mover,which as a steering control motor two 36W and two 150W as the main drive motor. Them togetherwith a large transmission ratio speed reducer,you can output up to 90N/ m of torque. In thisway, even if the AGV is driving the field in the ups and downs can also be"Rulvpingdi. Strengthen the type of body is not only spacious, but also to accommodate more equipment such as robots, infrared sensors, satellite locator.
This manual mainly describes the AGV chassis design ideas and principles, aswell as equipment safety check.
