1、 I 摘 要 随着机器向自动化、高速化的不断发展,机器人、机器手的日益兴起,连杆 机构的作用愈加显著,对它的设计与综合方法的研究也更加引起人们的兴趣。传 统的设计综合中多采用图解传或实验法,过程繁琐、设计周期长,可行性差,很 难准确实现设计要求,随着计算机技术以及数值计算方法的迅速发展,解析法得 到越来越广泛的应用。特别是近年来可视化程序开发技术的不断丰富与发展,使 得将连杆机构综合方法与综合过程程序化、 可视化就成为非常迫切而又有意义的 研究问题。 针对于这种情况,本文对平面连杆机构中应用最广的铰链四杆机构,利用数 值计算软件 MATLAB,文中以铰链四杆机构为研究对象,在对其进行运动分析的
2、 基础上,建立数学模型,应用 MATLAB/GUI 工具箱,开发出了平面四杆机构的运 动学分析系统软件。 关键词:四杆机构; 设计方法; MATLAB; 数学模型 II Abstract With the development of machine in the direction of automation and high speed,connecting rod machanism is making more notable impact on the developmeng of therobot day be day.As aresult,more antention will
