Elastic-plastic stresses in a thin rotating disk with shafthaving density variation parameter under steady-state temperature [PDF]

open access: yesKragujevac Journal of Science, 2014
Steady thermal stresses in a rotating disc with shaft having density variation parameter subjected to thermal load have been derived by using Seth's transition theory. Neither the yields criterion nor the associated flow rule is assumed here. Results are

Investigation of Wireless Sensor Deployed on a Rotating Shaft and Its Potential for Machinery Condition Monitoring [PDF]

open access: yes
Rotating shafts are the most critical component of rotating machines such as motors, pumps, engines and turbines. Due to their heavy duties, defects are more like developed during operation.

CFD Simulations on the Rotor Dynamics of a Horizontal Axis Wind Turbine Activated from Stationary

open access: yesApplied Mechanics, 2021
The adaptive dynamic mesh, user-defined functions, and six degrees of freedom (6DOF) solver provided in ANSYS FLUENT 14 are engaged to simulate the activating processes of the rotor of the Grumman WS33 wind system.

Determine variation of poisson ratios and thermal creep stresses and strain rates in an isotropic disc [PDF]

open access: yesKragujevac Journal of Science, 2016
Seth's transition theory is applied to the problem of thermal creep transition stresses and strain rates in a thin rotating disc with shaft having variable density by finite deformation. Neither the yield criterion nor the associated flow rule is assumed

Research on H7006C Angular Contact Ball Bearing Slipping Behavior under Operating Conditions

open access: yesLubricants, 2023
During operation, angular contact ball bearings exhibit slipping behavior, which accelerates bearing wear and reduces the bearing’s overall service life.

Large-uncertainty intelligent states for angular momentum and angle [PDF]

open access: yes, 2005
The equality in the uncertainty principle for linear momentum and position is obtained for states which also minimize the uncertainty product. However, in the uncertainty relation for angular momentum and angular position both sides of the inequality are

An automated methodology for performing time synchronous averaging of a gearbox signal without speed sensor [PDF]

open access: yes, 2007
In this paper we extend a sensorless algorithm proposed by Bonnardot et al. for angular resampling of the acceleration signal of a gearbox submitted to limited speed fluctuation.

A theoretical and experimental study of combined agricultural gantry unit with a mineral fertiliser spreader

open access: yesAgraarteadus, 2020
Operations to apply mineral fertilisers to the soil are an important part of practically every form of agricultural technology. The current global trend of transitioning to bridge and gantry-type agricultural systems leaves the unanswered relevant ...

Calculation of an Average Vehicle’s Sideways Acceleration on Small Roundabouts

open access: yesSensors, 2022
The calculation of the average sideways acceleration, based on speed and angular velocity on small roundabouts for a vehicle of up to 3.5 t gross vehicle mass, is described in this paper.

The angular speed distribution of randomly moving-particle group

open access: yesAIP Advances, 2022
Rotation is a common phenomenon in nature, although the detailed statistical principle behind it is seldom discussed. This article aims to inspire people to think about such problems.
