  spatial linkages
The structure of multi-regional trade flows: hierarchy, feedbacks and spatial linkages
      
The analysis provides insights into structure and spatial linkages that cannot be revealed from the more usual data sources (such as the distribution of employment by sector).
      
Complete balancing of the shaking moment in spatial linkages by adding planar noncircular gears
      
A balancing device is introduced, which can be applied for balancing spatial linkages which contain input links with revolving kinematic pairs.
      
The method consists in adding noncircular gears, proposed earlier to balance planar linkages, for the balancing of the shaking moment of spatial linkages.

n the Mechanisms Theory.most part of the equivalent relationship between the Burmester theory and the spatial four-bar linkages has been elucidated,but the geometric internretation of the pole Circles in the spatial case is in want of.To fuirill this gap,a cubic surface termed as guadric cone is proposed.An one-to-one correspondence between Bumester theory and its spatial equibalents is thus accomplished.

在平面四杆机构理论中利用极点圆绘制Burmester曲线,可以使概念清晰,计算大为简化,Burmester理论在空间四杆机构理论中的对应部分大部已被阐明,唯有与极点圆对应的几何图形还不清楚,因此与Burmester曲线对应的曲面(螺旋锥)只能按等两面角条件用解析方法求得,因为等两面角条件的数学表达式十分繁杂,直接求解这一复杂的方程往往难于取得进展,本文提出了解决这一问题的策略,获得Burmester理论在空间杆机构理论中的一一对应关系,从而使空间四杆机构的理论更为完整,概念更为清楚,计算也得以简化。

Tandem robots of closed chains are composed of several planar four-bar linkages and dimensional bar linkages. Defining the shortest open chain from the base to the operation terminal as a major chain, the kinematic analysis problem is turned to the sub-problems of the kinematic analysis of an open chain and several single closed chains. The kinematic analysis of the major chain can be done by the product exponentials formula. The positions and velocities of the major chain can be got from the kinematic analysis of the closed chains. The kinematic analysis of the planar four-bar linkage and dimensional six-bar linkage can be done by building up the structural equations. Finally, the results of the kinematic analysis of the major chain and that of the single closed chains are synthesized; And then the kinematic analysis of the whole tandem robot of closed chains is finished.

闭链级联式机器人由若干个平面四杆机构和空间杆机构串联而成,将这些杆机构中从基座到操作端最短的开链定义为主运动链,这样闭链级联式机器人的运动学分析就转化成了一个开链和若干个单闭链的运动学分析问题。主运动链的运动学分析采用指数积公式。主运动链的关节位置和速度信息可以由各个关节所在的单闭链的运动学分析得到。平面四杆机构和空间六杆机构的运动学分析可以通过建立闭链的结构方程来实现。最后综合主运动链和各个单闭链的运动学分析的结果即可得到主运动链关节空间与末端执行器位形空间的位置和速度映射关系,从而完成整个闭链级联式机器人的运动学分析。
