摘 要: 针对某型飞机外翼I大梁7#~8#肋间腹板的开口,为了保证开口后大梁的强度和刚度性能,提出了开口的加强方案;从理论上分析计算了加强方案的细节应力。计算表明该加强方案能满足大梁的承载要求。 Taking the holed web of the front spar in the outside wing for a serving aircraft, a jointstrengthened scheme is presented in order to maintain the strength and stiffness ability of the web and to assure security, The stress of the strengthened scheme is analyzed in theory using Finite Element Method (FEM).The results indicates that the strengthened scheme is suitable and security.
