摘　　要：针对化工压力容器的应力分析设计,从原理、方法及步骤进行了介绍,阐述了应力分析设计的特点和与常规设计的不同之处在于设计思想,分析设计放弃了传统的“弹性失效”准则,而采用以极限载荷、安定载荷和疲劳寿命为界限的“塑性失效”与“弹塑性失效”准则,允许结构出可控制的局部塑性区,允许对峰值应力部位作有限寿命设计。提出分析设计对新工艺、新材料、新结构和新工况的设备更具有科学性和可靠性。The principle, method and procedure of chemical industry pressure container design were introduced, the differences between the character of stress analysing design and conventional were discussed. The result showed that the analysing design is more scientific and reliable for the equipment with new technology , new material and new structure as well as new operating mode.
