S TATIC MULTIBODY ANALYSIS s aforementioned, the multibody analysis allows investigating the kinematic and dynamic behaviours of the investigated main landing gear. Thanks to such analysis, it has been possible to understand the trajectory of the landing gear subcomponents and the reaction forces acting on them as a function of the time. A multibody analysis is, for such reasons, often used to understand the kinematic of each sub-component, before the landing gear manufacturing. The multibody analysis carried out in this work has been developed in Adams® software environment [15]. The components have been modelled as rigid and linked reciprocally by means of ideal constrains, without considering their elasticity and the related friction.
