摘要
载荷放大系数法的基本原理是将给定载荷(谱)下的结构B基准寿命验证试验转化为给定B基准寿命下的结构剩余强度验证试验.载荷放大系数可由理论推导方法和试验方法确定.讨论了复合材料飞机结构全尺寸验证试验采用载荷放大系数法的原因、前提条件、1.
The basic principle of load enhancement factor is that,which transfere the B basic fatigue life certification test under given load spectrum into the residual strength certification test under given B basic fatigue life of composite airframes.Load enhancement factor can be detered by theoretical of testing methods.The application of load enhancement factors in the certification of composite airframes is also disscussed in this paper.
