Conference paper


A technique for the representation of the rotation operator in terms of only three free parameters based on the conformai rotation vector concept is described. It allows to develop efficient finite elements of mechanism components. The application to the deployment of a lightweight space structure cell demonstrates its high potential for analyzing 3-D flexible mechanisms with arbitrary topology.
