Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 The double‐gimbal control moment gyro (DGCMG) demands that the gimbal servosystem should have fast response and small overshoot. But due to the low and nonlinear torsional stiffness of harmonic drive, the gimbal servo‐system has poor dynamic performance with large overshoot and low bandwidth.

Joint Dynamics Modeling and Parameter Identification for Space Robot Applications
Mathematical Problems in Engineering, Volume 2007, Issue 1, 2007., 2007 Long‐term mission identification and model validation for in‐flight manipulator control system in almost zero gravity with hostile space environment are extremely important for robotic applications. In this paper, a robot joint mathematical model is developed where several nonlinearities have been taken into account.

FEM Analysis of Stress Distribution in the Hermetic Harmonic Drive Flexspline [PDF]
Strength of Materials, 2017 The paper deals with the numerical stress calculation in the flexspline tooth rim of the harmonic drive. Due to the complex geometry of the toothed ring in the flexspline, the teeth were modeled as a ring, which height corresponded to the particular stress concentration in the teeth.

DETERMINATION OF TORSIONAL STIFFNESS OF HARMONIC DRIVE [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2014 The aim of this study was to develop a simplified method for determining the torsional stiffness of harmonic drive. For this purpose, in this paper the flexspline of harmonic drive is studied by dividing it into three distinctive portions.

Buckling analysis of flexspline in harmonic gear reducers
Journal of Physics: Conference SeriesAbstract Harmonic gear reducers are widely used in the field of precision machinery due to their advantages of high transmission accuracy, large reduction ratio, and compact structure. As the core transmission component, the flexspline’s stability directly determines the performance and service life of the reducer.
