A Compliant Mechanism Synthesis Theory for Fostering Innovation of Micro Air Vehicles
Abstract
In this project, we have developed a compliant mechanism synthesis theory that incorporate a general framework for determining pseudo-rigid-body models, type synthesis algorithms (determining mechanism topology for a specific task) and kinetostatic analysis/synthesis. This theory has been implemented into computer codes with a graphical user interface. It has been applied to solve several structure design problems including design optimization of compliant transmission mechanism for flapping wing MAVs, a bistable buckling beam design and a robotic finger actuated using shape memory alloy actuators. For instance, we have developed a parameter optimization framework for determining the pseudo-rigid-body (PRB) model of cantilever beams. A novel concept of "PRB matrix" has been proposed to describe the general topology of an arbitrary PRB model. Based upon this synthesis theory, we have shown that compliant joints can significantly reduce the power consumption in flapping wing MAVs if they are designed to enhance the down stroke flapping motion.
