A lamina-emergent frustum using a bistable collapsible compliant mechanism
R Alfattani, C Lusk - Journal of Mechanical Design, 2018 - asmedigitalcollection.asme.org
This paper presents a new bistable collapsible compliant mechanism (BCCM) that is utilized
in a lamina-emergent frustum. The mechanism is based on transforming a polygon spiral
into spatial frustum shape using a mechanism composed of compliant links and joints that
exhibits a bistable behavior. A number of mechanism types (graphs) were considered to
implement the shape-morphing spiral, including 4-bar, 6-bar, and 8-bar chains. Our design
requirements permitted the selection of a particular 8-bar chain as the basis for the BCCM …
