基于ANSYS的压力容器的分析设计演示

Pressure vessel is one of the most important equipment, in order to design and evaluate pressure vessel, analysis design has been put forward by international, which standards of elastic-plastic failure. Based on a model of pressure vessel, this paper systematically describes the method of design analysis for the pressure vessel. Through ANSYS software simulation, the numerical calculation results under pressure and thermal load are calculated. Multiple representative paths are selected, primary stress, primary stress + secondary stress etc. are calculated by linearized stress, compared to standard. The index of primary stress + secondary stress is fail to pass because of big thermal stress. To reduce the temperature difference and thermal stress, it is necessary to enhance the height of insulating layer to improve insulation effect .
