极端工况下新型真空反应釜结构动力屈曲分析

Structural Dynamical Buckling Analysis for a Novel Vacuum Autoclave under the Extreme Operating Conditions

结构动力屈曲分析是壳体类压力容器结构设计中重要一步。建立了真空反应釜的有限元模型,并分别在真空、大气、高温和低温4个极端工况下进行了屈曲载荷计算,获得了模态变形情况以及较高的安全系数,结果表明真空反应釜的设计安全可靠。

The structural dynamical buckling analysis is an important step for the structural design of the pressure vessel with shell framework. An finite element model of vacuum autoclave was established and the buckling load calculations under the extreme operating eonditons, including vacuum, atmosphere, high-temperature and low-temperature, have been carried out to obtain the modal deformation condition and the safety factor. The results showed that the structure has a higher safety factor, which indicated that the vacuum autoclave design can meet the working conditon requirements.
