Vibration analysis of composite material-based landing gear system sandwiched with elastomeric material

This study evaluated the dynamic behavior of a landing gear system made from composite materials. The composite material used is a combination of epoxy resin reinforced with carbon fiber, with an elastomeric layer made from neoprene rubber sandwiched between them. Four different configurations of the elastomer layer were investigated through simulation. The results showed that incorporating elastomeric material in both the inner and outer layers of the landing gear reduces stiffness but increases the damping ratio of the system. The simulations, which employed both linear and bilinear spring models, were conducted to assess the impact of adding the elastomeric layer on the vibration response. It was observed that the vibration amplitudes in the system modelled with the bilinear spring were lower than those in the system modelled with the linear spring.
