ABSTRACT
3D printed material designs have a large capability in the functional aspect.
A cross-spring compliant joint is a hot topic in the sense of multipurpose
applications in various engineering fields. A combination of flexible materials
embedded in the structural form performs a motion of the system according
to deformation of parts elastically, which may fit to a specific engineering
purpose. In the present study, a traditional cross-spring pivot (CSP) was
improved to provide effectively frictionless and wear free in-plane motion.
The behavior of the joint was analyzed based on a non-linear FEA computer
analysis to focus the properties with various loading conditions. Improved
compliant joints will open a new door for designs of high-precision actuators
and robotic manipulators
