Study on Vibration Characteristics of the Deflection Cylinder of the Rail Grinding Motor and Its Optimal Design

open access: yes机车电传动, 2018
When grinding car is in the process of work, the grinding motor adjusts its grinding angle by deflection hydraulic cylinder, and severe vibration will appear when the cylinder is working.

Positive and negative deflection-angle coulomb scattering

open access: yesPhysics Letters B, 1975
Abstract The decomposition of the Rutherford amplitude into positive and negative deflection-angle contributions shows how Fraunhofer diffraction for charged-particle scattering is moved away from forward angles.

Non-equatorial deflection of light due to Kerr–Newman black hole: a material medium approach

open access: yesEuropean Physical Journal C: Particles and Fields
We explored the effect of space-time geometry on the trajectory of light rays in the context of a charged, rotating black hole. We derived an analytical expression for the deflection of light rays in Kerr–Newman space-time geometry, using a material ...

Airstream Deflection Across a Cylindrical Surface

open access: yesInternational Scholastic Journal of Science, 2016
A cylindrical airstream was blown across a cylindrical surface. The deflection angle, peak speed, and asymmetry of the airstream were measured while changing the location of the cylinder relative to the center of the wind column, and while changing the ...

Nonlinear Dynamics Modeling and Analysis of Underwater Mud-Penetrator Steering System

open access: yesIEEE Access, 2018
Adopting underwater mud-penetrator to thread the steel wire is one of the important steps in the current wreck salvage process, which is safer and more efficient than threading with manpower by the diver. This paper first establishes the kinematics model

Extreme value statistics of CMB lensing deflection angles

open access: yes, 2015
The smaller the angular scales on which the anisotropies of the cosmic microwave background (CMB) are probed the more important their distortion due to gravitational lensing becomes. Here we investigate the maxima and minima of the CMB lensing deflection field using general extreme value statistics.

Effects of Inflow Deflection Angle on the Stall Formation Mechanism and Flow Field Structure in a Vertical Axial-Flow Pump

open access: yesMachines
The influence of inflow angle on the stall characteristics of a vertical axial flow pump is investigated numerically by solving the unsteady Reynolds-averaged Navier–Stokes equations.

Cowl Deflection Angle in a Supersonic Air Intake

open access: yesDefence Science Journal, 2009
A numerical study for a two-dimensional mixed compression supersonic air intake with different cowl deflections has been made with and without back pressure. Numerical simulations have been made with RANS solver using a k-w turbulence model. Overall flow field existing inside intake has been captured which indicates the change in flow field with cowl ...

Measurement Method of Whole Mechanical Automatic Vertical Drilling Tools

open access: yesApplied Sciences
The inaccurate positioning of a plat valve is a crucial factor affecting the efficiency and safety of drilling operations. Because of the complicated structure of vertical drilling, it is difficult to obtain the actual position of a plat valve during the
