Abstract
针对应用于风洞试验模型支撑的绳系并联机器人的设计需求,采用实验和理论建模相结合的方法,研究绳阻尼对绳系并联机器人动力学特性的影响。首先,为了准确地定量描述绳阻尼,设计了一套测量绳索阻尼的实验装置,通过实验得到了不同参数下的绳阻尼比;其次,考虑了绳阻尼,对绳张力进行建模,并提出了考虑绳阻尼的绳系并联机器人的动力学建模方法;最后,分析了绳阻尼对绳系并联机器人动力学特性的影响。结果表明:绳阻尼对绳系并联机器人动力学响应的影响主要体现在响应幅值上,绳直径越大,绳阻尼对绳系并联机器人动力学响应的减振作用越明显。当绳阻尼系数大于0.6 N·s/m时,不论绳直径粗细如何,绳阻尼对绳系并联机器人动力学特性的影响不能忽略。国家自然科学基金(基金号11472234,11702232,11072207);;\n中央高校基本科研业务费(20720180071
