Temperature effect on selected mechanical properties of rocks of Skalka locality
Konečný, Petr
Results of research of temperature effect on selected mechanical properties of rock of Skalka locality are discussed.
Theoretical Dependence of Temperature of Burning Coal and Wood Particles on Conditions of Fluidized bed combustion
Svoboda, Karel
The report brings presentation and solution of two theoretical models for estimation of temperature of burning particles of low-ash coals (smaller particles) and high ash coals with particles above 1 mm in fluidized bed combustion. The attention is focused mainly on effects of fluidized bed temperature, operating pressure and size of particles on difference between fluidized bed (bulk) and burning particle temperature.
High temperature dynamical thermomechanical analysis
Černošková, Eva ; Černošek, Z. ; Holubová, J.
DTMA was used for measurements of NBS 711 model glass. Results were compared with measurement of DSC, TMA and viscosity.
Study of biodiversity and account of haematophagous dipterous insects, mainly mosquitoes, in PLA Palava and Litovelské Pomoraví
Gelbič, Ivan ; Minář, Jan ; Olejníček, Jiří
Changes in the biodiversity of haematophagous insects, mainly mosquitoes and effect of artificial flood on the account of mosquitoes were studied in PLA Palava. Global changes of temperature on the biodiversity of mosquitoes in PLA Palava and Litovelské Pomoraví were studied too.
Contribution to experimental research of thermo-mechanical behavior of tram wheel rubber segment
Pešek, Luděk ; Vaněk, František ; Veselý, Jan ; Cibulka, Jan
This contribution deals with press-tensile dynamic tests of tram wheel rubber segments. The evaluation of dynamic quantities was performed using hysteresis loops of force response versus loading displacement. The obtained dynamic behavior of the segments will be used for their numerical modeling in vibro-acoustic finite element tram wheel model. For research of thermo-mechanical interactions of elastomers in dynamic loadings, the inner temperatures were measured by use of single ended bead-type thermistor.
Evaluation of damping for two-component material mixture on the test samples at different temperatures
Pešek, Luděk ; Veselý, Jan ; Vaněk, František ; Cibulka, Jan
The report deals with the experimental evaluation of inner damping of a two-component mixture (NBR and NBR/BR) that is proposed for a damper production. The tests were done on two defined samples for temperature range from -40oC up to 100oC and frequency range up to 7kHz. The method of testing was proposed for the evaluation according to American standards SAE J1637 and ASTM E756-98.
