First, the Digital Mock-up of the of landing gear system in a C.A.D. software has been created, then the experimental structural stiffness of the leaf spring has been validated using the FEM tools MSC.Patran/Nastran. Finally, the entire model has been imported in MSC.ADAMS environment and, according to the certifying regulations, several multi-body simulations have been performed varying the heights of fall and the weights of the system. The results have shown a good correlation between numerical and experimental tests, thus demonstrating the potential of a multi-body approach. Future development of the present activity will probably be an application of the methodology, herein validated, to other cases for a more extensive validation of its predictive power and development of virtual certification procedures.}, type={Artykuły / Articles}, title={Drop test simulation for an aircraft landing gear via multi-body approach}, URL={http://www.czasopisma.pan.pl/Content/84886/PDF/06_paper.pdf}, doi={10.2478/meceng-2014-0017}, keywords={landing gear, drop test, multi-body, leaf spring, ADAMS}, }
