摘要:

研究了具有被动关节的机械臂刚度矩阵的计算问题。它提出了显式的解析表达式和一个有效的递归程序,适用于一般情况下,并允许获得所需的矩阵,无论是在分析或数值形式。所开发的技术和它的能力,以产生奇异和非奇异的刚度矩阵的优势,处理两个Stewart-Gough平台的刚度建模的应用实例说明。

英文摘要:

The paper focuses on stiffness matrix computation for manipulators with passive joints. It proposes both explicit analytical expressions and an efficient recursive procedure that are applicable in general case and allow obtaining the desired matrix either in analytical or numerical form. Advantages of the developed technique and its ability to produce both singular and non-singular stiffness matrices are illustrated by application examples that deal with stiffness modeling of two Stewart-Gough platforms.
