Due to the rapid development in the manufacturing of high
precision mechanism. It is required to reduce spending on its
manufacturing and (due to the friction). On the other it is very
important to achieve the same target with light weight and no
frictions. The all above objectives can be obtained by building the
machine to move as one body by using the elastic hinges.
The main purpose of this research is to accuracy of eight-six bar
mechanism -linked by fixed link , before and after replacing
revolute hinges with elastic ones.
most of companies wish to decrease maintenance and on the other
hand having the same target with low weight and no friction
although it may cost more, when a machine is built. Using
flexural(also flexure) hinges in a system, at least, leads to all
of
these advantages. Considering a planar mechanical system consists
of double seven bar mechanism with revolute joints, 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 novel system
through large bending displacements in the flexure (flexural) hinges.
