Energy based efficiency of adaptive structure systems

This study analytically investigates the behavior of a coupled, unloaded/loaded actuator–mechanism system, which is the main element of a modern adaptive structure. The analysis is performed from an energy transfer perspective. It couples the actuator to a compliant mechanism and takes into account interactions between this mechanized system and an applied load. Analytical relationships are developed that describe energy transfer between the actuator and the mechanized structure. The methodology is general and can be applied to a myriad of loaded, adaptive structure systems. Results are consistent with existing energy based techniques and provide a fundamental insight into the behavior of adaptive structure systems. It is shown that the design of such a structure must consider the interaction between these basic elements. This body of work extends existing research by developing a methodology that can be used to optimize a mechanized structure based on interactions between its driving actuator and its external load.
