Abstract

Static balance eliminates the actuation stiffness of flexure mechanisms and thereby reduces the motor effort and unwanted heat production. However, this typically comes at the cost of lowered support stiffness and stroke. This paper aims to show that the maximum stresses in the flexures may be reduced as well by static balance. Therefore, thicker flexures can be used, paradoxically leading to an increased support stiffness by static balance. In a case study of a parallel flexure mechanism we shown an increased support stiffness of 11%, while the measured actuation stiffness reduces by more than 95%. This shows that a tradeoff between actuation and support stiffness is avoidable.
