摘　　要：利用自制的飞机起落架磁流变减震器动态性能测试数据,对磁流变减震器动力学模型进行了辨识。并在此基础上,对起落架建立了动力学模型,利用此模型,设计了天棚控制器并利用Simulink进行了仿真分析。仿真结果显示,所设计的磁流变减震器在4D级机场跑道上滑跑时,其所控制的起落架相对位移、起落架垂直相对速度及机轮动载荷具有较好的控制效果,为磁流变减震器的实际应用提供了理论基础。The self-made aircraft landing gear magnetorheological（MR） damper dynamic performance test data is utilized to identify the dynamic model of MR damper. On this basis, the landing gear dynamics model is established, by using this model, a skyhook damper controller is designed and simulation analysis is carried out using Simulink. The simulation results show that the designed MR damper has better control effects in terms of the landing gear relative displacement, the vertical landing gear relative speed and the dynamic load of landing gear when taxiing on the 4D airport runway, which provides a theoretical basis for the practical application of the MR damper.
