Abstract— The present work deals with the problem of
detection of suspension rating which is frequently
encountered in structural synthesis of kinematic chains.
A new method which incorporates all essential feature
of matrix method easy to compute & reliable is
suggested in this paper. It is capable of detecting rating
in all types of planar kinematic chains. Many methods
are available to the kinematic chain to detect suspension
rating among chains & inversions but each has own
shortcoming. Most of the study to detect suspension
Rating is based on hamming matrix & multiple
equation method. This method is based on joint value &
jerk absorbing capacity of kinematic chain. This
method is proposed up to six bar kinematic chains & its
inversion. C.N.Rao and A.C.Rao have been reported
methods to predict the performance and rate the
kinematic chains and mechanism among several
configurations. In the present work a methodology is
used which is based on the influence of type of links,
type of joints present in a kinematic chain to predict
the performance of kinematic chains without carrying
out the dimensional synthesis.

I. INTRODUCTION
The problem of detection of suspension rating
between two kinematic chains has been the subject
matter of investigation for a long time. This method
is proposed that if the link has more jerk absorbing
capacity & to produces more kinetic energy then this
kinematic chain is more suspension.
Nikunj Yagnik and Anurag Verma[1]
proposed a method to rate kinematic chain. A.C. Rao,
Raju D. Varada[2] used hamming matrix to detect
isomorphism. In this method forming the joint value
matrix by the help of two directly connected link.S.
Shende & A. C. Rao[8] proposed Mach Theory in
this field. After forming this matrix any one link is to
be fixed & give a motion or jerk to another link.
Calculate the motion of another connected link
except that fixed or grounded link. Comparison of
characteristic coefficient of the adjacency matrix of
the corresponding inversion of kinematic chain is
considered to be suitable for this purpose.
Application of the joint value & link
assortment method for structural synthesis & analysis
of planer kinematic chain has been proven to be an
effective & systematic approach in the suspension
rating. Many of the method which is to be used for
detecting the suspension rating are very lengthy &
calculation is more complicated.
. One of the most important and challenging
problem in structural synthesis of kinematic chain is
to identify the possible structural suspension between
given chains. Kinematic synthesis is an essential step
at the first stage of designing of a machine, as it
represents creation of mechanism to achieve a desired
set of motion characteristics. Ali Hasan , Khan
R.A[9] used Mach theory in this field. Many
researchers have directed their efforts to study
various aspects of mechanisms, Machine designer
have been synthesizing kinematic chains
unconsciously. A lot of literature related to
suspension rating detection and detection of distinct
mechanism (DM) is available but still there is scope
for an efficient simple and reliable method and this
paper is an attempt in this direction vary important
problem involved structure analysis of chains is the
determination of distinct mechanism of a chain and to
detect suspension rating among kinematic chains.
Attempts have been made in the past to solve this
problem, and a number of algorithms proposed by
crossly, mainly based on the Graph Theory, are
available in the literature. Most of these methods are
based on link adjacency matrices or Distance
matrices which was first introduced by Freudenstein
and Dobrajansky. In this paper we generate a
