椭圆形舱口角隅有限元网格自动划分研究

Research on automatic meshing for elliptic hatchway corner

针对椭圆形舱口角隅网格的自动划分方法,采用MSC.Patran二次开发语言PCL,编制了椭圆形舱口角隅网格的自动划分系统。应用此系统对多个不同尺寸的椭圆形角隅进行了热点应力分析,并且将其与相应尺寸的圆形角隅热点应力作了比较。计算结果表明:椭圆形舱口角隅自由边处的热点应力比圆形舱口角隅处小得多。

This paper proposes the automatic meshing method for the elliptic hatchway corners. Such meshing system is developed based on PCL which is the secondary development language of MSC.Patran software. The hot spot stresses on elliptical hatchway corners with different sizes are analyzed and compared with stresses on circular ones with corresponding sizes. The results are much smaller than stresses on circular ones. show that the hot spot stresses on elliptical hatchway corners
