采用应力分析的方法对某在用压力容器进行强度校核

Using Stress Analysis Method to Verify the Strength of a Pressure Vessel in Use

某企业使用的矩形灭菌柜在使用过程中产生局部腐蚀,进行缺陷评级时,因凹坑的存在无法满足进行无量纲参数计算的限制条件。文中采用有限元应力分析的方法对缺陷进行强度校核,判断其是否影响此压力容器安全使用。

The rectangular sterilization cabinet used by an enterprise experienced local corrosion during use,and during defect rating,the presence of pits did not meet the limitations for dimensionless parameter calculation.The finite element stress analysis method is used in the article to verify the strength of defects and determine whether they affect the safe use of this pressure vessel.
