Modeling and Fatigue Characteristic Analysis of the Gear Flexspline of a Harmonic Reducer
Mathematics, 2022 The failure of harmonic gear drive is mainly caused by the fatigue fracture of flexible wheels and the fatigue damage of flexible bearings. In this paper, the stress sensitivity and fatigue life characteristics of flexible wheels with thin-walled vulnerable components are studied. Firstly, the structure of the flexible wheel of a B3-80 general harmonic

International Journal of Aerospace Engineering, Volume 2018, Issue 1, 2018., 2018 We propose a Bayesian‐based reliability framework for a satellite‐equipped harmonic gear drive (HGD) mainly addressing two unsettled issues in existing research works, that is, an efficient aggregation method for multilevel system with imbalanced information and the multisource data fusion in a hierarchical structure. The proposed approach improves the

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.
