Виртуальные испытания двойной несущей системы Пизанской башни
Довнар, С. С.; Лапука, А. Д.; Шведова, Д. Н.; Маненок, А. В. (БНТУ, 2022)FEA simulation of the double load-bearing system (LBS) for Pisa Tower is provided. Cylindrical trunk (T-LBS) is surrounded by 6-stage column system (C-LBS) in the telescopic manner. T-LBS is found out as the main object to bear the tower’s weight. Trunk is rigid and low-stressed. CLBS is partially (about 44 % of mass) hanging on the trunk by pliable cornices. Slender C-LBS is ...2023-01-26 -
Концепция конверт-усиления полимербетоном несущей системы 5-осевого многоцелевого станка с ЧПУ
Довнар, С. С.; Макаренко, К. Д.; Гринкевич, А. Г.; Хруцкая, Т. А. (БНТУ, 2022)Load-bearing system (LBS) of cubic-shaped multipurpose 5-axis CNC machine is investigated. Results of FEM-simulation are involved. Low stiffness of the machine could be improved by polymer concrete pouring into cavities of cast-iron structural parts. More perspective design pattern is to embrace machine LBS by concrete envelopes, inserted one-inside-other. It should provide outer ...2023-01-24
