| Abstract: | The compliant mechanism and its character are described.One of typical model of the force-displacement inverter obtained by topology optimization are analyzed and studied.Under the conditions of the components of the model are rigid bodies,the model of geometrical advantage and mechanical advantage can reach a maximum.This means that force and displacement output efficiency is maximal.Taking the truss displacement inverter as basic model,the objective function is optimized through the analysis of the geometrical advantage of the inverter.With the technique of structural mechanics analysis,the size of the inverter is optimized by numerical method. |
