SIDE PRESSURE IN THE CLOSED FORM DURING THE COMPACTION PROCESS OF LIME-SAND MIXTURE
Journal Title: Tribologia - Year 2011, Vol 240, Issue 6
Abstract
The article presents an analysis of the impact of compacted granular materials, for example, lime-sand mixture (used in the manufacture of lime-sand brick), the side walls in a closed form. Based on experimental studies, the side pressure coefficient ξ was determined. Its value allows the calculation of the side pressure on the projected bulk medium height, depending on the applied compaction pressure.

INVESTIGATION OF FRICTION AND WEAR MECHANISMS OF PVD-TiAlN COATED CARBIDE AGAINST Ti6Al4V TITANIUM ALLOY USING A PIN-ON-DISC TRIBOMETER
In this paper, the tribological behaviour of the TiAlN coated carbide inserts in dry sliding against Ti6Al4V titanium alloy was investigated. A pin-on-disc device was used to record both the friction coefficient and the...
DISSIPATION AND ACCUMULATION OF ENERGY AS FACTORS CONDITIONING STABILITY OF FRICTIONAL COUPLES
Wear and stability of frictional couples are presented as a function of dissipation and accumulation of energy. Such couples are treated as open thermodynamic systems and processes occurring in them are described on the...
Wpływ założeń modelu obliczeniowego na wyniki obliczeń hydrodynamicznych łożysk wzdłużnych
Na przestrzeni ostatnich lat opracowanych zostało wiele modeli obliczeniowych przeznaczonych do wyznaczania własności hydrodynamicznych łożysk wzdłużnych. Umożliwiają one uwzględnienie w analizach obliczeniowych wielu is...
