We study a planar mechanical system generated by two six-bar
mechanism with revolute joints, then we link them by revolute joint
to become one system . After that we replace each revolute joint
with super elastic hinge. The main purpose of this pa
per is to
elaborate a mathematical method able to estimate the deviations of
the considered system before and after replacing revolute hinges,
taking into account that new system creates large additional
deviations .
