  closed kinematic chain
A closed kinematic chain, like an arm that operates a crank, has a constrained movement space.
      
Its closed kinematic chain and parallel linkage structure give it great rigidity and a high force-to-weight ratio.
      
To derive the control scheme, kinematics and dynamics of the robot when it forms a closed kinematic chain is discussed.
      
The steering control mechanism used in all helicopters, including the CL-327, is a complex closed kinematic chain often called the swashplate mechanism.
      
However, one major problem in controlling this kind of manipulator is that, due to its closed kinematic chain and parallel-link constrained structure, it is impossible to derive an explicit kinematic solution.

In this Paper the direction cosine matrices and conditions of geometrical identities are applied to derive the crank existing conditions and the translation conditions about the output link of the mechanism for the overconstrained mechanisms RRRE, RRPE and RCE, Furthermore, the method is also applied to the spatial crank mechanisms with a single degree of freedom such as RRRRE,RRPRE and RCRE, which are similar to the mechanisms mentioned above inmotion character.

In this Paper the direction cosine matrices and conditions of geometrical identities are applied to derive the crank existing conditions and the translation conditions about the output link of the mechanism for the overconstrained mechanisms RRRE, RRPE and RCE, Furthermore, the method is also applied to the spatial crank mechanisms with a single degree of freedom such as RRRRE,RRPRE and RCRE, which are similar to the mechanisms mentioned above inmotion character. Thus, the significance of the crank existing conditions for theoverconstrained mechanisms is extended. According to the research about the closed spatial motion links 6R, RRPPRRand RCCR with a plane of symetry, the following results are obtained: the condi-tions under which the mechanisms above become overconstrained constant velocitybicrank mechanisms are equivalent to the crank existing conditions of the over-constrained mechanisms RRRE, RRPE and RCE respecdively. Therefore, the over-constrained constant velocity bicrank transmission mechisms 7R, RRPRPRR,RRRPRRR and RCRCR are obtained. These mechanisms can be applied to the intersecting axes or interlacing axes transmissions.

本文采用方向余弦矩阵和机构运动的几何等同条件,导出RRRE RRPE和RCE过约束空间机构的曲柄条件及其输出构件的平动条件,进而分别演化出运动特点完全相同的RRRRE RRPRERRRPE和RCRE单自由度空间曲柄机构,从而拓广了过约束机构曲柄条件的意义。通过对具有对称面结构的6R、RRPPRR和RCCR空间闭式运动链的研究,得出它们成为过约束等角速双曲柄机构的条件分别等同于RRRE RRPE和RCE过约束机构曲柄条件的结论。从而得到可用于相交轴或交错轴间的6R、RRPPRR、RRPRR、RCCR和5R过约束等角速传动双曲柄机构及特殊的7R、RRPRPRR、RRRPRRR和RCRCR等角速传动空间双曲柄机构。

Spatial motion of a rigid body can be seen as a screw motion of the body along a specific axis. In accordance with the above principle the screw theory is presented to analyse the relative motion of a robot here. The screw motion equation presented is also suitable for closed chains, i. e. spatial mechanisms.
