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。 关键词：自动引导车；农用机械；伺服电机；减速机；焊接。 ABSTRACT Automatic Guided Vehicle(AGV) is a
