低压加热器非径向接管大开孔补强应力分析
|
摘要
为了分析低压加热器非径向接管大开孔处结构强度,采用有限元分析模型,计算低压加热器应力场。利用ANSYS软件的应力线性化功能,得到了低压加热器壳体和接管的薄膜应力和弯曲应力;依据压力容器分析设计标准,对其局部应力强度结果进行评定,据此判定开孔处的结构强度。结果表明,接管大开孔处结构强度满足分析标准要求。
In order to analyze the structural strength of large opening of non-radial pipe of low-pressure heater, the stress field of low-pressure heater is calculated by finite element analysis model. By using the stress linearization function of ANSYS software, the membrane stress and bending stress of the shell and nozzle of low pressure heater are obtained, and the local stress intensity results are evaluated according to the analysis and design criteria of pressure vessel, and the structural strength at the opening is determined accordingly. The results show that the structural strength at the large opening of nozzle meets the requirements of the analysis standard.
