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 ...

SIMULATION TESTS TO FORECAST SELECTED PROPERTIES OF THIN-WALLED CASTS OF DUCTILE IRON DOMES

Thin-walled dome casts (hemispheres) with a wall thickness of 4.2 and 10.3 mm made of ductile iron underwent simulation tests within the frame of forecasting the tendency to create residual stresses, casting defects, the shaping of structures and ...
