Assessment of Dynamic Landing Loads by a Hybrid Multibody / Full Finite Element Simulation Approach

Kurzfassung

This paper describes a new process for the detailed assessment of the impact of aircraft ground manoeuvres 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 of two reference aircraft with their corresponding finite element models. 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 the results of the parameter studies will be presented.
