STUDY ON DIGITAL SIMULATION AND TEST VERIFICATION FOR DEBRIS IMPACT ON GFRP COMPOSITE

Abstract

Abstract: This paper summarized the literatures related to debris impact on aircraft structures to obtain the velocity and energy parameters required for radome structures to bear, conducted runway debris impact test on composite panels, and built LS-DYNA model to simulate the test. By tuning the parameters in the simulation model, the test result can be reflected in the model for the composite panel. And through the user programming, the behavior of debris can also be finely repeated in the computation model. In future, in the process of radome to runway debris impact computation, all other parameters can remain unchanged in the simulation model, only the composite panel model needs to be replaced. Thus, we can get a set of quick and reliable method to get the rational result from simulation results based on LS-DYNA models for runway debris impact.
