This paper presents results of research performed in the field of semi-active suspensions for advanced landing gears and optimization of their associated design parameters to achieve minimum weight, maximum comfort under strict requirements with respect to safety and even increase lifetime by reducing the loads during landing impact and taxiing. A detailed mechanical model is derived for an existing aircraft (AIRBUS A300) which will be used for simulating the standard design as well as the active optimized landing gear. The simulation is performed with SIMPACK, DLR's prime multibody computer code. Results will be presented on using the multi-objective parameter optimization software ANDECS. The design case study will concentrate on taxiing of a flexible aircraft. Reduction of the so-called 'beaming effect' (e.g. dynamic coupling of runway excitation with elastic fuselage eigenmodes) is the major design goal.
