This paper presents an approach for the kinematic design of a rapier drive mechanism containing a spatial mechanism and analyses rapier motion curve. Kinematic design and analysis equations are derived and then the link lengths of the spatial mechanism are calculated in order to satisfy the critical rapier positions inside and outside the shed. In this way, the portions of one loom revolution, during which the rapiers are inside and outside the shed, are determined. The rapier motion curve is obtained by using kinematic analysis equations. It is shown that the position of the oscillating link in the spatial mechanism and the loom main shaft angle at which the rapier enters the shed have the most significant effect on the rapier motion curve. The gear ratio has also some effect on the rapier motion curve. Different rapier motion curves are obtained by changing these parameters and the suitability of these curves for rapier motion is discussed.

The kinematics analysis is carried out on a kind of 3-urps parallel mechanism (pm) with 6-dof. The positional inverse solution and Jacobean matrixes which is used to analyze the dexterity of mechanism are derived. Condition number is used as evaluating indicator of dexterity in this article, and its’ three-dimensional graphs are drawn when this mechanism in different attitudes. It is indicated that dexterity of moving is excelled than the rotary movement’s for this pm. The optimum dexterity can be obtained in the center of mechanism’s workroom, which can be applied to further characteristic analysis and kinematic design of mechanisms.
