| Abstract: | The crash characteristics are an important requirement of army helicopters. It is a main technical measure that the bottom fuselage structure possesses high impact energy-absorbing capability. The study of crash impact behavior of typical composite structure components is carried out the first time in China in this paper. Based on the components study, an optimum new structural assembly combining composite wave beams and thick honeycomb elements is put forward, which possesses high impact energy-absorbing capability. Theoretical calculating and testing are combined to do this research work. The validation and effectiveness of estimating and theoretical calculating are demonstrated by the results of tests. Also, the study result of this paper has been applied to the practical design of helicopter structures. |
