CAE在彩电后壳浇注系统中的应用 总被引:1,自引:0,他引:1
应用美国AC-TECH公司的C-MOLD软件对29寸(74cm)彩电后壳的模具浇注系统进行了计算机辅助工程(CAE)分析。结果表明,采用计算机C-MOLD软件对充模进行动态模拟,可直观地了解彩电后制品所需充模的最大压力和锁模力,并能确定熔融前锋料流速度的分布和熔接痕的位置分布,它为指导大型注塑模具的设计提供了科学依据,有较高的应用和研究价值。 相似文献

2,3,5-Triphenyl-2H-tetrazolium Chloride and 2,4,6-Tri(2-pyridyl)-s-triazine on the Corrosion of Mild Steel in HCl 下载免费PDF全文
Electrochemical measurement, quantum chemical method, and scanning electron microscopy (SEM) were performed to investigate the inhibitive effect of 2,3,5-triphenyl-2H-tetrazolium chloride (TTC) and 2,4,6-tri(2-pyridyl) -s-triazine(TPT) on the corrosion of mild steel in lmol.L^-1 HCl at room temperature. Impedance spectroscopy measurement showed that the polarization resistance increased and that double layer capacitance decreased with the increase in the inhibitive concentration, and the results of potentiodynamic polarization showed that the inhibitors suppressed both cathodic and anodic processes of steel corrosion without change in the mecha-nism. Higher the orbital density distribution strength of the lowest unoccupied molecular orbital, higher is the molecule dipole, and lower energy gap between the energy of the highest occupied molecular orbital and the energy of the lowest unoccupied molecular orbital resulted in higher inhibitory efficiency. The results of SEM analysis showed that the metal-was protected from aggressive corrosion by the addition of TTC and TPT. 相似文献
