由于大多数固体火箭发功机通常用于武器系统。往往是一次性使用,因此文中使用了“服役寿命”这一名词。术文介绍了固体火箭发动机服役寿命分析的一般程序,简述了一般程序的各个环节:几何形状、载荷的确定、材料性能、应力分析、损坏方式的确定、损坏判据、强度分析和老化,最后介绍了几个寿命分析的实例。 Since most solid rocket generators are commonly used in weapon systems. Often one-time use, the term “service life” is used. This paper introduces the general procedure of service life analysis of solid rocket motor, and briefly describes all aspects of the general procedure: geometry, load determination, material properties, stress analysis, determination of damage methods, damage criteria, strength analysis and aging, Finally, several examples of life analysis are introduced.
