摘　　要：根据运输类飞机拦阻着舰的特点,以载机与舰船间多体动力学关系作为基础,搭建了一套由载机-航母-起落架-拦阻器组成的多体动力学系统仿真模型。结合近舰区风场等外部环境模型,使系统不仅能够反映出运输类飞机基本的着舰动力学特性,还可研究复杂环境中载机-航母的适配性问题。在以该模型为基础的研究工作中,重点分析了着舰速度、载机重量、下滑轨迹、风扰动、甲板运动等因素对运输类飞机拦阻着舰过程的影响。仿真结果表明:风扰动及甲板运动对载机着舰过程的影响最为严重,其余扰动则会对着舰过程中某些相关参数产生较为明显的影响。为下一步将要开展的运输类飞机着舰控制系统的研究工作提供了一定的参考依据。According to the characteristics of landing process on aircraft carrier of carrier-based transport aircraft, a simulation model for the carrier-aircraft-undercarriage-barrage multi-body dynamics system was established based on the multi-body dynamic relationship between the aircraft and the carrier. In combination with the model of the wind fields near by carrier, the model not only reflects the basic dynamical characteristics of landing process on aircraft carrier of carrier-based transport aircraft, but also does some research on the integration for the carrier-aircraft sys- tem. The work based on this model system focuses on analyzing the effects of various factors, including the landing velocity, transport weight, glide path, wind disturbance and deck motions. Simulation results, presented in Figs. 2 through 9 and Tables 1 through 3, and their analysis demonstrate preliminarily that, （1） wind disturbance and deck motions are the greatest harmful factors for the transport aircraft＇ s landing on the aircraft carrier; （2） for spe- cific characteristics of the transport, other disturbances bring significant effects.
