孔结构热接触弹塑性数值分析

Thermal contact elastic-plastic numerical analysis of hole-structure

应用ANSYS对实际孔结构进行了热载荷下接触模型弹塑性数值分析,建立了孔边接触弹性模型、孔边接触弹塑性模型和模拟弹性边界孔边接触弹塑性模型等三种不断改进的模型,分别模拟了结构的弹性弹塑性以及固支边界和弹性边界。通过对计算结果的分析比较,表明弹性边界的弹塑性模型更为精确可靠。

ANSYS system is used for thermal contact elastic-plastic numerical analysts of hole- structure. In order to eliminate the influence of boundary and obtain a precise and reasonable model, hole- border contact elastic model, hole-border contact elastic-plastic model and simulating elastic-boundary hole-border contact elastic-plastic model are established in improvement. Some comparable examples show that simulating elastic-boundary hole-border contact elastic-plastic model is better and . more reasonable.
