摘要
空间连杆机构与平面机构相比,具有构件少,结构简单的优点,但由于其运动副形式的复杂性和多样性,特别是难于想象和构思,发展比较迟缓。文中介绍了工程实践中采用空间连杆机构在石油钻头试验机上获得满意效果的情况,并对该空间连杆机构的有关特性进行了分析。
As to Planar Linkages,Spatial Linkages has the advantages:small amount of linkages,simple structure.But because of its complexity and diversity of elements,and the difficulty how to think about them,the development of Spatial Linkages is slow.In the article,we indroduce how to use Spatial Linkages to solve a difficult question in petroleum drilling experiment.Then we research some geometric and konematic function property of this Spatial Linkages.
