SYSTEM AND METHOD FOR CONTROLLING VIBRATION OF ENGINE MOUNT FOR ACTIVE CANCELLATION AND ISOLATION BY FEEDBACK AND FEEDFORWARD CONTROL FOR AIRCRAFT ENGINE MOUNT VIBRATION

摘要

PROBLEM TO BE SOLVED: To provide active cancellation and isolation by feedback and feedforward control for the vibration of an aircraft engine mount.;SOLUTION: An engine mount structure (300) is provided with active vibration mechanisms (36) which are attached in the vicinity of an engine mount (30) to prevent engine vibration from propagating into an engine mounting structure (32), (for example, a wing or a fuselage structure of an aircraft). Additionally, sensors (40/42) are provided in an engine (34) and/or a wing/fuselage structure (32) to provide control signals to the active vibration mechanisms (36) so that the active vibration mechanisms (36) react to the sensed data to minimize vibration transmissibility from the engine (34) into the wing/fuselage (32).;COPYRIGHT: (C)2007,JPO&INPIT
