ANALYSIS OF THE STATE OF STRESS IN CAST BODIES, COVERS AND WEDGES OF THE WEDGE GATE VALVES USED IN GAS NETWORKS

Numerical analysis was carried out to establish the operating stress distribution in softsealed gate valves cast from ductile iron EN-GJS-400-15 for the gas network of PE pipes. The analysis was carried out with ANSYS software, based on data and d...

AN OPTIMISING NUMERICAL ANALYSIS OF THE DISTRIBUTION OF STRESSES AND DISPLACEMENTS IN THE RUBBER CURING PROCESS OF CHECK VALVE BALLS

Decreasing the density of check valve dip balls by nearly 30% results in significant decrease in the wall thickness of the domes from which the balls are assembled. During the high pressure curing process a risk occurs of excessive deformation or ...

Building foundations for the diffusion mechanism of ceramic mould drying

An attempt was made to develop a mathematical model and apply this model in numerical analysis to the drying process of multi-layer ceramic moulds used in investment casting. The numerical analysis carried out in a FLOW-3D program was meant to ser...

The evaluation of microporosity and mechanical properties in high strength aluminum alloys with the use of numerical analysis and computed tomography

One of the aspects of sustainable development is the reduction of the concentration of CO2 in the atmosphere. This could be achieved for example by the reduction of fuel consumption. That is why the research for the new construction and...
