The original proposed type synthesis method shows the systematic development of the possible kinematic chains
and the mechanism structures of the geared linkages with linear actuation and parallel connected chains, based on the known structural relationships used in the mechanism science , .
The compensations required to produce better racket velocity may appear along all the kinematic chain
As the wrench system of a parallel kinematic chain
is the linear combination of those of all its legs in a general configuration, any leg-wrench system in a E = PKC is a sub-system of its wrench system.
(5) geometric synthetic errors of each of the axes that make up the kinematic chain
of the MT.
The motion [x.sub.C] of the CoM is derived from the motion of the whole kinematic chain
by using a different Jacobian matrix [J.sub.P] that takes into account only the ankle and knee joints.
It is possible to perform a general motion of a working item of the robot through kinematic chains
with 6 degrees of freedom, for example robot CINCINNATI (Fig.3)--contains 6 kinematic pairs (rotating).
A kinematic chain
with a specified number of links and degree -of -freedom will have the same number of design parameters irrespective of the link assortment.
Beginning and ending on a known TBM allowed checking the positional repeatability of the first and last points in each stop-and-go or kinematic chain
. Using a rapid static technique 10 true error points were collected on the field.
One causality offered by which cervical trauma could result in TMJ symptoms involves a complex kinematic chain
of events beginning with injury to cervical muscles, subsequent myospasm, posterior hyperextension of the head, reflex adaptation of head posture, increasing tension on hyoid musculature, inferior and posterior movement of the mandible, altered muscle accommodation to facilitate occlusal contact, with resultant masticatory muscle bracing followed by spasm.
In figure 2 the following legend is used: 1--prop with vertical guides, 3-- electric motor that drives the feed kinematic chain
, 3--feed box (reducing gears), 4--feed screw, 5--hydraulically balanced enclosure, 6--sheaves and cables system, 7--hydraulic cylinder.
A planar simple joint kinematic chain
is a kinematic chain
only composed of simple joints, if there is a kinematic chain
containing multiple joint, called a multiple joint kinematic chain
, for example, a multiple joint kinematic chain
which is shown in Figure 2(a).
