Abstract

A spiral pulley based mechanism is used to passively balance the energy between the morphing structure and actuation system. Applying the energy balancing concept has the potential to improve the performance of the actuation system by reducing the external energy consumption. In the current study, the energy balancing concept is adopted in a morphing design. A conceptual design of the integration is introduced with gears added between the spiral and load pulleys. The stiffness of the morphing structure is measured and a test rig is built to demonstrate the mechanism. Optimisation is performed to find the design parameters of the passive energy balancing mechanism.
