An analytical formulation for the lateral support stiffness of a spatial flexure strip

M Nijenhuis, JP Meijaard… - Journal of …, 2017 - asmedigitalcollection.asme.org
A flexure strip has constraint characteristics, such as stiffness properties and error motions,
that govern its performance as a basic constituent of flexure mechanisms. This paper
presents a new modeling approach for obtaining insight into the deformation and stiffness
characteristics of general three-dimensional flexure strips that exhibit bending, shear, and
torsion deformation. The approach is based on the use of a discretized version of a finite (ie,
nonlinear) strain spatial beam formulation for extracting analytical expressions that describe …
