Abstract EN
Due to the short duration of impulsive impact of an aircraft during touchdown, a traditional landing gear can only achieve limited performance.
In this study, a magnetorheological (MR) absorber is incorporated into a landing gear system; an intelligent control algorithm, a human simulated intelligent control (HSIC), is proposed to adaptively tune the MR absorber.
First, a two degree-of-freedom (DOF) dynamic model of a landing gear system featuring an MR absorber is constructed.
The control model of an MR damper is also developed.
After analyzing the impact characteristic during touchdown, an HSIC is then formulated.
A genetic algorithm is adopted to optimize the control parameters of HSIC.
Finally, a numerical simulation is performed to validate the proposed damper and the controller considering the varieties of sink velocities and sprung masses.
The simulations under different scenarios show that the landing gear system based on the MR absorber can greatly reduce the peak impact load of sprung mass within the stroke.
The biggest improvement of the proposed controller is over 40% compared to that of skyhook controller.
Furthermore, HSIC exhibits better adaptive ability and strong robustness than skyhook controller under various payloads and sink velocities.
