Abstract:
An assessment of a frictional helicopter blade attachment with regard to its influence on the dynamics of the in-plane blade motion is presented. For detailed system analysis, a 3D finite element model with contact modeling has been created and validated using preexisting test data. Using the insights gained from 3D finite element simulations, a reduced order model suitable for dynamical simulations is derived and parameterized. Eventually, the reduced order model for the blade attachment is...     »
