Inverse Identification of the Loading Applied by a Tire on a Landing Gear Wheel

This study aims at identifying the loading applied by a tire on a landing gear wheel for an inflation case. A full scale test instrumented via stereo-DIC (Digital Image Correlation) and strain gages is performed. A 3D finite element model of the wheel is developed and a parameterization of the tire-rim loading is proposed based on model reduction techniques. This parameterization is further used for an inverse identification of the loading parameters. This approach leads to a simpler and more robust problem that can easily be extended to more complex service loadings.
