舰载机-拦阻器耦合系统动力学建模与仿真分析

拦阻过程是舰载机着舰过程中的核心环节。舰载机的着舰滑跑响应除受舰载机自身特性、起落架缓冲特性影响外，拦阻器的拦阻特性对舰载机着舰滑跑动响应也具有至关重要的影响。本文提出了舰载机-拦阻器联合仿真分析模型的建模方 法，建立了包含完整的MK7-3拦阻器刚柔耦合动力学模型和某型舰载机动力学模型为一体的舰载机-拦阻器刚柔耦合动力学系统。数值仿真分析结果表明，本文建立的舰载机-拦阻器耦合系统模型能够很好地描述舰载机着舰过程中与拦阻器之间的交互作用特征，舰载机着舰滑跑 数据的计算结果与实验结果吻合。

Dynamics Modeling and Simulation Analysis of Coupled Carrier-Based Aircraft and Arresting Gear System

Arrestment process is very essential when the carrier-based aircraft is landing on the deck of an aircraft carriers. Landing response of the carrier-based aircraft is not only dominated by given landing weight of the aircraft and buffering properties of the landing gear system, but also determined by mechanism performance of the arresting gear system. The modeling method for the carrier-based aircraft coupled with the arresting gear system is presented. The detailed numerical dynamics model of the carrier-based aircraft coupled with the MK 7-3 arresting gear is established by using flexible-rigid coupled dynamics method. Validation of the model is demonstrated by numerical example. Interaction between the carrier-based aircraft and the arresting gear system can be described precisely by using the established model. Analytical results match well with the test data.
