description | <p>This work is dedicated to the study of the large-displacement behaviour of a
spiral spring. Parameters that influence the local torsion stiffness of the
beam that constitutes the spiral are varied and their effect is studied.
Cross-sectional shape, orthotropic material orientation and prestress are the
three classes of parameters that are varied. The effect that the local change
in torsional stiffness has on the overall behaviour is illustrated in a
linearised way by comparing in-plane and out-of-plane stiffnesses, and
nonlinearly, by inspecting a graphical representation of the potential energy
field of the system. Several embodiments composed of multiple spirals are
showed to illustrate how the understanding of the nonlinear behaviour could
be exploited in conceptual design of compliant mechanisms.</p> |
