1、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
2、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。关键词:自动引导车;农用机械;伺服电机;减速机;焊接。ABSTRACTAutomatic Guided Vehicle (AGV) is an economical, efficient, stable and logistics transportation solutions, from the automotive industry has gradually penetrated
3、 into the various 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 not yet achieve the desired state. The design characteristics of agriculture, the A
