双圆弧弧齿锥齿轮重合度研究

open access: yesJixie chuandong, 2013
The contact ratio is main effective factor on mesh characteristic of double circular arc profile spiral bevel gear(DCAPSBG).The overlap contact ratio of DCAPSBG ensures its continuous transmission.Based on the contact ratio definition of spiral bevel ...

Magnetoresistance Effect in Spin-Polarized Junctions of Ferromagnetically Contacting Multiple Conductive Paths: Applications to Atomic Wires and Carbon Nanotubes

open access: yes, 2004
For spin-polarized junctions of ferromagnetically contacting multiple conductive paths, such as ferromagnet (FM)/atomic wires/FM and FM/carbon nanotubes/FM junctions, we theoretically investigate spin-dependent transport to elucidate the intrinsic ...

Anomalous inversion effect of hydraulic properties in contacted asperity fractures: insights from laboratory flow experiments

open access: yesFrontiers in Earth Science
Multi-physics modeling of underground rock mass fractures rarely accounts for contact asperities, thus hindering fracture-related permeability estimation during geofluid migration processes.

Influence of linear profile modification and loading conditions on the dynamic tooth load and stress of high contact ratio gears [PDF]

open access: yes
A computer simulation for the dynamic response of high-contact-ratio spur gear transmissions is presented. High contact ratio gears have the potential to produce lower dynamic tooth loads and minimum root stress but they can be sensitive to tooth profile

Elastic properties of isotropic discrete systems with skew contact normals [PDF]

open access: yes, 2019
The macroscopic elastic properties of discrete assemblies are fundamental characteristics of such systems. The contribution uses homogenization procedure based on equivalence of virtual work between the isotropic elastic continuum and the discrete system

Analytical Expressions of the Efficiency of Standard and High Contact Ratio Involute Spur Gears

open access: yes, 2013
Simple, traditional methods for computation of the efficiency of spur gears are based on the hypotheses of constant friction coefficient and uniform load sharing along the path of contact. However, none of them is accurate.

Numerical Study of Drop Motion on a Surface with Wettability Gradient and Contact Angle Hysteresis

open access: yes, 2013
In this work, the motion of a 2-D drop on a surface with given wettability gradient is studied numerically by a hybrid lattice-Boltzmann finite-difference method using the multiple-relaxation-time collision model.
