إن الهدف الرئيسي للعمل هو بناء منظومة رياضية قادرة على تقييم الازاحات للمنظومة المعتبرة قبل و بعد التبديل آخذين بعين الاعتبار أن المنظومة الجديدة ينتج عنها إزاحات إضافية (ناتجة عن المرونة العالية) كبيرة.
The main purpose of this research is to elaborate a mathematical apparatus able to estimate the deviations of the considered system before and after replacing revolute hinges taking into account the real performance of the novel system through large bending displacements in the flexure (flexural) hinges.

The too many uses of the five- bar mechanism and the seven-bar
one in novel mechanical systems, lead us to develop the action of
the both mechanisms. Compacting the both mechanisms gives
ability new mechanism with dual action. It is that the new o
ne is
better in achieving but It's more difficult in studying from the to
separately. The developing of the action appears in decreasing the
maintenance and having the same goal with low weight and no
friction. The experiment refers that using flexural hinges in a
system at least leads to all of that advantages. We have a plane
mechanical system consisted of five bar mechanism and seven bar
mechanism, with revolute joints. Then, we replace each revolute
joint with super elastic hinge. In this way, we have a gate to build a
system,strongly recommended, to achieve the same goal using
minimum energy. The main purpose of this paper is to elaborate a
mathematical mechanism able to estimate the deviations of the
considered system before and after replacing revolute hinges,
taking into account the real performance of the novel system
through additional large extra displacements in the flexural hinges.
We have a plane mechanical system
consisted of pantograph mechanism and four bar one, with revolute
and sliding joints. Then, we replace each revolute joint with super
elastic hinge. So that, we have a system, strongly recommended, to
achieve the
same goal using minimum energy. The main goal of
this paper is to elaborate a mathematical mechanism able to
estimate the deviations of the considered system before and after
replacing revolute hinges, taking into account the real performance
of the new system through additional large displacements in the
flexural hinges.
The most of companies wish to decrease maintenance and have the
same target with low weight and no friction even costs much
money, when a machine is built. Using flexural(also flexure) hinges
in a system, at least, leads to all of that advantages.
We have a
planar mechanical system consisted of seven and six bar
mechanism, with revolute joints, after that we replace each revolute
joint with super elastic hinge. Doing so we have a gate to build a
system, strongly recommended, to achieve the same goal using
minimum energy. The main purpose of this paper is to elaborate a
mathematical apparatus able to estimate the deviations of the
considered system before and after replacing revolute joints taking
into account the real performance of the new system through large
bending displacements in the flexure (flexural) hinges.
The importance of pantograph mechanism and four Bar one leads
to improve of two mechanisms. As we said in last papers,
decreasing maintenance and having the same goal with low weight
and no friction in nowadays artificial applications, appears as
a
needed need. The experiment refers that using flexural hinges in a
system at least leads to all of that advantages. We have a plan
mechanical system consisted of pantograph mechanism and four
bar one, with revolute and sliding joints. Then, we replace each
revolute joint with super elastic hinge. In this way, we have a gate
to build a system, strongly recommended, to achieve the same goal
using minimum energy. The main goal of this paper is to elaborate
a mathematical mechanism able to estimate the deviations of the
considered system before and after replacing revolute hinges,
taking into account the real performance of the new system through
additional large displacements in the flexural hinges.
In this paper we have a plan mechanical
system consists of two pantograph mechanisms, with revolute and
sliding joints, linked by fixed link . Then, we replace each revolute
joint with super elastic hinge. In this way, we have a system,
strongly recommended, to achieve the same goal using minimum
of energy.
