| As the most important combat weapon of the aircraft carrier, carrier-based aircraft canachieve all-weather operations and perform all sorts of tasks. Compared with land-basedaircraft, it is more difficult and dangerous to land safely the carrier-based aircraft on thelimited deck space. Thus the research on the aircraft arresting system is extremelyimportant for ensuring the safety of carrier-based aircraft landing.First of all, the author introduces basic knowledge about the carrier-based aircraftarresting system and it includes the composition and operational principle of the arrestingsystem and theoretical knowledge of the kink-wave on the arresting cable.Secondly, the author has studied on parameter identification about the model of MRdampers in MR buffering system. And then the author has utilized the genetic algorithm andthe hybrid algorithm mixed the damped least square algorithm and the simulated annealingalgorithm to identify the parameters of the sigmoid model, further more, the author hascompared and analyzed the identification result. Simultaneously, the author has establishedthe polynomial model which reveals the relationship between the identified parameters andthe current and has confirmed the model order, and the result shows that the cubic polynomialmodel is the best model and it fits the identified data. Then the author has verified theadaptability and accuracy of the calculated mechanics model by calculating the error betweenexperimental data and computational result from the model.Finally, the mechanical modeling and simulation on the carrier-based aircraft arrestingsystem has been finished. Firstly, the author describes the force situation of the carrier-basedaircraft and expounds the change law of arresting force on carrier-based aircraft. Secondly,the author describes the formation process of the kink-wave and the configuration of thekink-wave and establishes the model of the kink-wave. Afterwards, the author has establishedthe mechanical model of the carrier-based aircraft arresting system, and then the author hasutilized the fuzzy control algorithm in the MR buffering system to control the damping forcefrom MR damper. Finally, the author has finished the simulation in the case that the carrier-based aircraft are affected with or without the kink-wave, and has compared andanalyzed the simulation result. The result shows that the kink-wave can not be neglected atthe carrier-based aircraft arresting process. |
