摘要
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。
Simulation model of six-degree of freedom of carrier-based aircraft catapult was established according to its dynamic characteristics.In this model,carrier,aircraft and landing gears were regarded as multi-body,the coupling relationships within these multi-bodies were illustrated.The influences of deck motion,atmospheric disturbance at sea level and the disturbance wind ahead of the bow were also considered.Simulation results of a carrier-based aircraft catapult launch were given,which show that this model reflects the coupling reaction among carrier,aircraft and landing gears and describe the dynamic characteristics of catapult launch properly.
