Abstract

Shape memory materials have different shapes, volume, stiffness, and electrical resistances in response to the change of temperature or electromagnetic fields. In this research, we developed methods for designing planar linkages that can be actuated with springs made from shape memory materials.The resulting linkages are called the configuration memory linkage systems, which can memorize linkage configurations at different temperatures. The change in ambient temperatures would effect the change in the stiffness of the springs and thereby moves the linkage from one configuration to another. Homotopy continuation methods are used to solve the system of polynomial equations for linkage design. | 52 pages
