From LMS International
In the Super Rig at Goodrich Corporation's landing gear facility in Oakville, Ontario (Canada), LMS engineering consultants subjected a body landing gear prototype assembly for the Airbus A380 to Experimental Modal Analysis (EMA). After suspending the 12,000 pound body gear 12 feet high above concrete, they applied burst-random and stepped-sine excitation up to 1,000 Newton force levels. The major landing gear mode shapes extracted from the test data, both in static and fully extended stroke, supported structural studies at Airbus and helped engineers verify finite element (FE) models generated by Goodrich's Landing Gear division.
