في هذا البحث لدينا منظومة ميكانيكية مستوية مكونة من آلتي رسم
خرائطيتين و بمفاصل دورانية و انسحابية, و موصولتين بوصلة ثابتة من الطرفين.
هدفنا بناء منظومة متينة جديدة تنجز العمل بوتيرة أسرع و طاقة أقل.
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.

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
