拦阻着舰过程中，舰载机着舰距离短、载荷大，有必要确定起落架的真实动态响应。针对拦阻着舰的复杂性，以某型舰载机为研究对象，通过LMS.Virtual.Lab Motion建立了该舰载机拦阻着舰动力学模型。考虑飞机在自由飞行状态下，以不同舰上结合速度以及不同下沉速度挂索着舰的情况。通过仿真分析，挂索时的下沉速度越大，舰上结合速度越小，主起落架受载越大，前起落架则呈现相反的情况。分析结果可为舰载机拦阻着舰过程研究以及起落架结构设计提供参考。
During the process of arresting landing, it is necessary to determine the true dynamic response of landing gear，because the landing distance of carrier-based aircraft is short and the load is large. Aiming at the complexity of arresting landing, the dynamics model of a carrier aircraft arresting landing was established by LMS.virtual.Lab Motion. Under the condition of free flight, the aircraft landed with different horizontal ground speeds and different sinking speeds. Through the simulation analysis, the larger the sinking speed or the smaller the horizontal ground speed, the larger the main landing gear load, nose landing gear presents the opposite situation. The analysis results can provide a reference for the research on the arresting landing process and the design of landing gear structure of the carrier-based aircraft.
