应用CAESAR Ⅱ进行管道应力分析的几点原则

Several Principles of Using CAESAR Ⅱ to Analyze Piping Stress

CAESARⅡ是一款基于结构力学杆状单元进行有限元分析的专业管道应力分析软件,其遵循的标准包括ASME B31.3工艺管道、ASME B31.1动力管道、以及BS806等等。对于国内化工热力行业,一般采用ASME B31.3、ASME B31.1进行管道应力分析校核的计算,本论文着眼于利用CAESARⅡ软件采用ASME B31.3标准进行管道应力分析的情况,对分析计算过程中的一些参数提出了一些需要注意的地方。

ASME B31 series standards has been recognized by more and more industry users for its serious and science , CAESAR Ⅱwas a professional piping stress analysis software by finite element analysis , based on bacilliform unit in structural mechanics.The following standards included ASME B 31.3 process piping , ASME B31.1 power piping , BS806 , etc.For the domestic chemical and thermodynamic industry , the great mass of designers using ASME B 31.3 to calculate the piping stress.The piping stress analysis with ASME B 31.3 code , some notice point about the parameter in the piping stress analysis were put forward.
