Structure Design and Magnetic Field Simulation of Non-contact Nutation Reduction Motor
Jixie chuandong, 2019 In order to solve the problem of weak stiffness of flexible wheels and more mechanical friction in existing robot harmonic reducer motors, a new type of nutation reducer motor is proposed by combining nutation deceleration motion with magnetic meshing ...

How flagellated bacteria wobble
Physical Review ResearchThe wobbling motion of flagellated bacteria significantly influences their swimming behavior, yet its dynamics remains poorly understood, primarily due to the difficulty in tracking the 3D orientations of both the flagellar bundle and the cell body. Here,

Damping-Based Attitude Control of a Gyrostatic Satellite in Resistive Media [PDF]
Journal of Applied and Computational MechanicsThe orientation of a satellite that contains a passive, internal mass damper about a stationary point is studied. The satellite is moving in a resistive medium and influenced by gyrostatic torque (GT).

The principal moments of inertia calculated with the hydrostatic equilibrium figure of the Earth
Geodesy and Geodynamics, 2017 As an indication of the Earth's mass distribution, the principal moments of inertia (PMOI, i.e., A, B, C) of the Earth are the basic parameters in studies of the global dynamics of the earth, like earth nutation, and the geophysics.

Optimization design of radial meshing nutation magnetic gear system based on D-APSO algorithm
Advances in Mechanical EngineeringTo combine the high transmission ratio of nutation drives with the non-contact power transfer of permanent-magnet gears, this paper proposes a novel radial meshing nutation magnetic drive system (RMNMD) and investigates its magnetic coupling mechanism ...

Perturbed Motions of a Rigid Body Similar to Pseudoregular Precession in the Lagrange Case [PDF]
Journal of Applied and Computational MechanicsThe paper investigated the perturbed rotational motions of a rigid body, close to pseudoregular precession in the Lagrange case. It is assumed that the direction of the rigid body angular velocity is close to the axis of dynamic symmetry of the body; the

Influence of shell initial perturbational motion conditions on its nutation angle value
Military Technical Collection, 2013 The article investigates the influence of initial conditions of projection of a shell from a cannon bore providing that cannon bore and shell have perfect axial symmetry, and shell precessional motion occurs only due to gravity action, as well as gun tube substantial wear and warming up when firing.
