摘要
为解决施药器械在山地复杂地理环境下长期、可靠、高效工作问题,设计了一款山地果园喷药机器人.利用ANSYS软件对末端执行器内齿轮传动进行静态分析,研究输出啮合齿面应力分布、应变云图及其对应的最大值,与齿轮端面许用应力对比;研究末端喷药机构入口压力、喷嘴孔径、雾化锥角与雾滴粒径之间的关系,以实现喷嘴的合理选型,为末端喷药机构参数化设计提供理论依据.
Abstract
In order to solve the problem of long-term,reliable and efficient operation of pesticide application equipment in mountainous complex geographical environment,a mountain orchard spraying robot was designed.The static analysis of the internal gear transmission of the end effector was carried out by using ANSYS software.The stress distribution,strain cloud diagram and corresponding maximum value of the output meshing tooth surface were studied,and compared with the allowable stress of the gear end face;The relationship between the inlet pressure of the end spraying mechanism,the nozzle aperture,the atomization cone angle and the droplet size was studied to achieve a reasonable selection of the nozzle.It provides a theoretical basis for the parametric design of the end spraying mechanism.
