Contact dynamics analysis of nutation drive with double circular-arc spiral bevel gear based on mathematical modeling and numerical simulation [PDF]

open access: yesMechanical Sciences, 2021
This paper describes a dynamic mathematical model of a new type two-stage nutation drive system with double circular-arc bevel gears. The dynamic displacement–vibration coupling model takes into account the gyro torque and side clearance of the nutating ...

The Dynamics of Plant Nutation [PDF]

open access: yesScientific Reports, 2020
AbstractIn this article we advance a cutting-edge methodology for the study of the dynamics of plant movements of nutation. Our approach, unlike customary kinematic analyses of shape, period, or amplitude, is based on three typical signatures of adaptively controlled processes and motions, as reported in the biological and behavioral dynamics ...

Dynamic modal analysis of double-sided meshing nutation drive with double circular arc spiral bevel gears [PDF]

open access: yesMechanical Sciences, 2020
In order to reduce the vibration of the double-sided meshing nutation drive with double circular arc spiral bevel gears, the dynamic modal of the nutation system is analyzed.

Nutation resonance in ferromagnets [PDF]

open access: yesPhysical Review B, 2020
The inertial dynamics of magnetization in a ferromagnet is investigated theoretically. The analytically derived dynamic response upon microwave excitation shows two peaks: ferromagnetic and nutation resonances. The exact analytical expressions of frequency and linewidth of the magnetic nutation resonance are deduced from the frequency dependent ...

Parameter Self-Adjusting Single-Mode Fiber Nutation Coupling Algorithm Based on Fuzzy Control [PDF]

open access: yesSensors
The free-space optical communication fiber coupling system requires improved coupling efficiency through the fiber nutation algorithm. However, traditional fiber nutation algorithms suffer from issues such as fixed parameters and limited correction range.

Shapiro like steps reveals molecular nanomagnets’ spin dynamics

open access: yesAIP Advances, 2015
We present an accurate way to detect spin dynamics of a nutating molecular nanomagnet by inserting it in a tunnel Josephson junction and studying the current voltage (I-V) characteristic.

Plant nutation relies on steady propagation of spatially asymmetric growth pattern [PDF]

open access: yesQuantitative Plant Biology
Nutation is one of the most striking and ubiquitous examples of the rhythmic nature of plant development. Although the consensus is that this wide oscillatory motion is driven by growth, its internal mechanisms remain to be fully elucidated. In this work,

The Kinematics of Plant Nutation Reveals a Simple Relation between Curvature and the Orientation of Differential Growth. [PDF]

open access: yesPLoS Computational Biology, 2016
Nutation is an oscillatory movement that plants display during their development. Despite its ubiquity among plants movements, the relation between the observed movement and the underlying biological mechanisms remains unclear.

Free Core Nutation observed by VLBI [PDF]

open access: yes, 2013
The signature of free core nutation (FCN) is found in the motion of the celestial intermediate pole in the celestial reference frame and in the resonance behaviour of the frequency-dependent Earth tidal displacement in its diurnal band.

The effect of nutation angle on the flow inside a precessing cylinder and its dynamo action [PDF]

open access: yesThe Physics of Fluids, 2022
The effect of the nutation angle on the flow inside a precessing cylinder is experimentally explored and compared with numerical simulations. The focus is laid on the typical breakdown of the directly forced m =  1 Kelvin mode for increasing precession ...
