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

elastic hinge. So that, we have a system, strongly recommended, to

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.
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
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.
