Measurement and Analysis of Industrial Forklifts Vibration Levels for Unit Load Testing Purposes

open access: yesApplied Sciences, 2021
Forklifts are one of the most common types of material handling equipment used in warehouses and distribution centers. Vibration generated by forklifts may have an effect on the performance of unit loads and product damage rates.

The Fractal Characterization of Mechanical Surface Profile Based on Power Spectral Density and Monte-Carlo Method

open access: yesE3S Web of Conferences, 2018
The analysis of rough surface morphology plays an important role in the functional characteristics of the contact surface of mechanical parts. Fractal geometry method is more accurate and sensitive than classical statistics model.

Generalized two axes model of a squirrel-cage induction motor for rotor fault diagnosis [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2008
A generalized two axes model of a squirrel-cage induction motor is developed This model is based on a winding function approach and the coupled magnetic circuit theory and takes into account the stator and the rotor asymmetries due to faults.

The non-negligible effect of magnetic holes on the magnitude-of-B magnetic power spectral density of the fast Alfvenic coronal-hole-origin solar wind at 1 AU

open access: yesFrontiers in Astronomy and Space Sciences
To estimate the effects of magnetic holes on the magnitude of B magnetic power spectral density, a 2-day interval of fast coronal-hole-origin plasma at 1 AU is examined. The magnetic holes are identified and removed from the magnetic time series, and the
