根据舰载机弹射起飞的特点,考虑了舰船、舰载机及起落架之间的相互作用和甲板运动、海面大气扰流以及舰艏气流扰动对舰载机的影响;基于多体动力学理论,描述了舰船-飞机-起落架多体系统的耦联关系,建立了舰载机弹射起飞六自由度动力学模型。利用此模型,仿真了舰载机的弹射起飞过程。仿真结果表明,此模型能较完整地反映航母、舰载机和起落架之间的相互耦联关系,正确地描述了舰载机弹射起飞的动力学过程。
According to the launching characteristics of carrier-based aircraft launching, the interaction between ship, carrier-borne aircraft and landing gear and the influence of deck motion, surface turbulence and ship turbulence on shipborne aircraft are considered. Based on multi-body dynamics Theory, describes the ship-aircraft-landing gear multi-body system of the coupling relationship established carrier-based aircraft takeoff six-degree-of-freedom dynamics model. Using this model, the launching process of carrier-based aircraft was simulated. The simulation results show that this model can more completely reflect the mutual coupling relationship between aircraft carrier, carrier aircraft and landing gear, and correctly describe the dynamic process of take-off of carrier-based aircraft.
