A hybrid approach for the analysis of aircraft ground loads

Kurzfassung

This work presents a new process for the detailed assessment of the impact of aircraft ground maneuvers on local structural loads. The process is comprised of two core elements, a multibody simulation analysis and a subsequent direct transient response finite element analysis. The multibody simulation is used for the simulation of aircraft landing loads. These loads are then applied to an aircraft finite element model, via a direct transient response, for a more detailed analysis of the aircraft dynamic behavior at the desired points of interest. The process has been developed using landing simulations with three different finite element models of a 150-passenger aircraft. The objective of the current activities is to study the effect of major simulation and modelling parameters on the detailed aircraft dynamic response. In the paper, the process and detailed results are presented.
