Молекулу N,N-дифенилциклогекса-2,5-диен-1,4-диимина можно рассматривать как структурный фрагмент макромолекулы полианилина в окисленном состоянии. Сравнительный расчѐт структуры этой молекулы проведѐн методами молекулярной механики, полуэмпирической квантовой механики и ab initio (HF DFT). При расчѐте методом DFT использованы функционалы ωB97X-D3, ωB97M-V, ωPBE-D3, M11, M06HF-D3, BLYP-D3, M05-2...

This study used finite element analysis software DEFORM-3D to analyze the preform formability and die stress in pre-forming process of forging automobile transmission components. The materials are AISI- 5120 alloy steel JIS-SKD61 mould steel, respectively. research investigated phenomenon folding defects at end final process. First, as shape under pre-formed channel was designed change, its clo...

Cold forging of automotive parts in high strength steel causes pressure on the die. The or heavy load reduces a die life and accuracy forged parts, so prediction more accurate helps us to design optimum dimensions process. In this report, precise frictional coefficient was measured by ring compression test predict cold upsetting steel. experimental results indicated μ about 0.19 within height r...
