Abstract The article presents the results of choosing tires for driving wheels cotton-growing row-crop tractors during inter-row cultivation. track surfaces 15.5-38, 16.9R38, 420/85R38 and 18.4R38 are compared on a rigid base. hard base maximum pressure soil, soil density tire tread depth were determined in experimental studies. When tires, their average q av max pressures determined. In order ...

coeffcient of  friction  (cof)  for  rubber parts  is one of  the key parameters in their interaction with solid rough surfaces (micrometer to millimeter scales),  such  as  tire-road  interactions. cof  of  rubber  depends  on  viscoelastic properties of rubber, roughness characteristics of the counter-part surface, and process variables such as contact nominal pressure and sliding speed. due ...

Experimental research on agricultural tractor movement, acquisition and archiving of kinematic features is an important issue in the analysis braking acceleration processes. The obtained traffic parameters depend environmental conditions, condition type pavement, load, tire pressure area tire-pavement cooperation. factor, particular process, determined by coefficient friction enabling assessmen...

A finite element modeling of tire using Ansys is used to analyze the free vibration of radial pneumatic tires. The natural frequencies and mode shapes of pneumatic tires are investigated. The effects of some parameters such inflation pressure, tread pattern, ply-angles and thickness of belts on the natural frequency of tires are investigated. Keywords— natural frequency, inflation pressure, tre...

SUMMARY Through analysis of earlier research and some recent on-road testing it is demonstrated that, with adequate precaution, accurate measurement of tire/pavement noise using on-board sound intensity (SI) can be accomplished with two intensity probes oriented vertically. As in the single probe method, SI is measured in the airflow alongside of a vehicle at locations opposite the leading and ...

The correlations between pavement texture and tire pressure with the actual tire-road contact area were first investigated according to static characteristics; on this basis, influence mechanisms of speed friction coefficient systematically explored from angle coupling system dynamics via self-developed dynamic testing tire-pavement friction. By integrating above factors, BP neural network meth...

Barotrauma is identified as one of the leading diseases in Ventilated Patients. This type of problem is most common in the Intensive Care Units. In order to prevent this problem the use of Data Mining (DM) can be useful for predicting their occurrence. The main goal is to predict the occurence of Barotrauma in order to support the health professionals taking necessary precautions. In a first st...

A review of the climatological and storm-time behaviour of the ionospheric slab thickness is presented based on long-time observations at a European mid-latitude site, Dourbes (50.1°N, 04.6°E), and on published results from other studies. An operational electron density and slab thickness monitoring system, established to provide real-time characterisation of the local ionospheric dynamics, is ...
