摘　　要：把压力容器设计中应力分类和应力评定的规则同结构优化中的满应力设计概念结合起来，建立了广义满应力设计方法，并用这一方法对超高强度钢制宇航用球形容器的上下接管部位进行优化设计和制造。实际检测和试验表明，这一设计不仅比原设计减轻了重量，而且提高了爆破压力。The extended full design method was established based on the combination oftherules ofstress classification and stress as sessmentin pressure vesseldesign andthefullstress design conceptin optimum structure,andthe optimum design and manufac ture were madeforthe up and down nozzles in spherical vessels ofsuper highstrength pressuresteelforspaceflight.The practical check andtestshow thatthe design reducedthe weightofvessels and raised explosion pressure of vessels.
