DETERMINATION OF THERMAL CONDUCTIVITY OF COMPOSITE MATERIAL CONTAINING GLASS AND ALUMINOSILICATE MICROSPHERES FILLED WITH AIR
Journal Title: Збірник наукових праць Українського державного університету залізничного транспорту - Year 2018, Vol 175, Issue 9
Abstract
The article gives an analysis of the requirements for traditional heat-insulating materials. In connection with the introduction of new norms on energy saving, including in the residential sector, as well as increasing the requirements for the heat protection of buildings, the issue of the development of essentially new thermal insulation materials that meet the requirements of the time has become most urgent. One of these materials is liquid composite systems filled with glass and aluminosilicate microspheres based on polymer binders.

INCREASE SPEED TRAIN INTERCITY(+) BY REDUCING THE NUMBER LIMITATION
On the railways of Ukraine, the parameters of the state of the railway track and a number of other reasons lead to the need to reduce the speed relative to its maximum level. Especially large changes in speeds take place...
REFINEMENT OF DYNAMIC MODELS OF THE ROD SYSTEMS
The author considers the possibility of applying methods for reducing the dimensionality of dynamic models to rod systems with many degrees of freedom. The research object is the latticed tower. It should be noted that t...
PROBABILISTIC RELIABILITY ASSESSMENT OF GATE CHAMBERS ON ROCK FOUNDATION BY THE CRITERIA OF STRENGTH, OVERTURNING AND STABILITY AGAINST DISPLACEMENT OF THE GATE CHAMBERS ON THE EXAMPLE OF HYDRO SCHEMES OF THE DNIEPER CASCADE
This work further develops the method for assessing reliability of gate chambers by the criteria of stability loss against displacement and overturning, as well as floating up. The work considers the random nature of the...
SWITCH’S WEAR-RESISTANCE INVESTIGATION FOR OPERATING CONDITIONS OF KIEV UNDERGROUND RAILWAY
Maintenance of track and switches of differs significantly from main-line railway. This is caused by other operating conditions of rail track and switches. In underground railway used special project switches, also there...
DEVELOPMENT OF MEASURES FOR THE PROTECTION OF STRUCTURES OF RAILWAY TRANSPORT AGAINST ELECTROCORROSION UNDER ACTION OF ALTERNATING CURRENT LEAKAGE AND HIGH-VOLTAGE TENSION
The destructive effects of the corrosive effects of stray and leakage currents are observed in almost all industries. The question is the most relevant for the railways. It is known that direct (DC) leakage currents and...
