摘要
记者从发明人提供的背景资料中获得以下引述：“目前，有两个转动自由度和一个转动自由度的三自由度并联机构。”平移自由度是一类非常重要的低自由度并联机构。平行线MECHANI SM具有刚质量比大、承载能力高、结构紧凑等优点并且可以更有效地节省系统设计、制造和控制在应用中的成本金属切削等机械加工。
Abstract
Reporters obtained the following quote from the background information supplied by the inventors:“At present, a three-degree-of-freedom parallel mechanism with two rotational degrees of freedom and onetranslational degree of freedom is a very important class of lower mobility parallel mechanisms. The parallelmechani sm has the advantages of large rigidity-mass ratio, high load capacity, compact structure and thelike, and may more effectively save system design, manufacturi ng and control costs in the applications ofmachining such as metal cutting.
