Landing Gear System: Sensitivity Analysis&Optimization

Vito Primavera, EnginSoft

Getting to match the Landing Gear System (LGS) requirements is an essential task at the aim not only to guarantee a safe landing, but also to improve passengers comfort. At the same time, LGS design is addressed looking for more efficient engineeristic solutions, so the best trade-off has to be found in respect of all performances, sometime conflicting between them too.
The main objective of this activity is to investigate the behaviour of a LGS versus design parameters, establishing firstly a correlation between the design parameters and output performances, and secondly searching for optimized solutions.
At this purpose, a suitable LS-DYNA LGS finite element model has been integrated into modeFRONTIER. The following accomplishment of an efficient numerical campaign allowed to perform the sensitivity analysis and optimization.
