民机侧壁板抗鸟撞性能评估方法研究
Research on Evaluation Method for Bird Impact Resistance of Civil Aircraft Side Panels
摘要
Abstract
[Purposes]Bird impact resistance has always been one of the important testing fac-tors for aircraft airworthiness.In order to explore the bird impact resistance performance of civil aircraft nose side panel,three methods of rivet failure ratio assessment,energy method,and re-sidual bearing capacity assessment are used to evaluate.[Methods]The effectiveness of the nu-merical model was verified by simulating the bird impact behavior of three types of side wall pan-els by using PAM-CRASH software,and the reliability of the above method was evaluated ac-cording to the bird impact failure of the three test specimens.[Findings]The research results in-dicate that the lower the proportion of rivet failures,the better the bird impact resistance of the structure;When the proportion of rivet energy absorption increases and the proportion of skin energy absorption decreases,the anti-bird-collision performance of the structure is improved;Among the above methods,the residual bearing capacity evaluation method can realize quantita-tive analysis of the bird impact resistance performance.The lower the damage factor value,the better the bird impact resistance performance of the side wall panel.[Conclusions]By summari-zing the applicability and limitations of the bird impact performance evaluation method for side wall panels,this work provides valuable reference for the safety design and research and develop-ment of later civil aircraft.关键词
