IET Control Theory and Applications, 2009 This study addresses an axis-manoeuvring problem using two-axis rotational kinematics. The goal of two-axis rotational kinematics is to find a policy of rotating an arbitrary axis towards another arbitrary direction using only one or two rotations of ...

Mathematical Study on Local Fluid Rotation Axis: Vorticity is Not the Rotation Axis
2021A vortex can be intuitively recognized as the rotational/swirling motion of the fluids. The fascination of the phenomenon brought about many years of research to classify and identify the vortical structure. Vorticity was one of the first theories developed to identify the vortex.

Vibrations of a rotating membrane with unsteady rotations of the axis of rotation
Strength of Materials, 1990A method and algorithm are developed for numerical calculation of the vibrations of a rotating circular membrane with a rigid central insert. The vibrations are caused by plane rotation of the rotation axis with a variable angular velocity. A system of differential equations is obtained to describe the motion of the membrane in relation to the stress ...

The Determination of Rotation Axis in the Rotation Electron Diffraction Technique
Microscopy and Microanalysis, 2013AbstractMethods to determine the rotation axis using the rotation electron diffraction technique are described. A combination of rotation axis tilt, beam tilt, and simulated experimental diffraction patterns with nonintegers zone axis has been used. Accurate knowledge of the crystallographic direction of the incident beam for deducing the excitation ...

A new method for estimating the axis of rotation and the center of rotation
Journal of Biomechanics, 1999A new method is presented for estimating the parameters of two different models of a joint. The two models are: (1) A rotational joint with a fixed axis of rotation, also referred to as a hinge joint and (2) a ball and socket model, corresponding to a spherical joint. Given the motion of a set of markers, it is shown how the parameters can be estimated,

The principal motions in most cutting operations are rotations: mainly the rotation of the workpiece in turning, cylindrical grinding, etc., and the rotation of the tool in boring, milling, etc.
