摘　　要：运用有限单元法对PTA蒸汽管回转干燥机汽室进行了应力分析,并按照JB4732-95《钢制压力容器———分析设计标准》进行了应力强度评定。结果表明,采用德国AD规范设计该汽室是安全的,其设计结果偏于保守。The stress analysis was conducted with FEM for the steam chest of the PTA steam-tube rotatory dryers, and a stress intensity estimation was made based on JB4732-95 “ Steel Pressure Vessel——Standards of Analysis and Design” . The result shows that the designed steam chest with German AD code was safe, the design was a little conservative.
