摘要
针对流变力学的特点,在起落架上采用了间隙密封式环形截流口结构的缓冲器,并对其进行了力学分析,根据实际情况,对缓冲器的受力进行了简化;基于Bingham模型建立了缓冲器的力学模型,并对其进行了仿真分析。仿真结果显示,该力学模型能准确地反映起落架缓冲器的工作特点,适用于起落架缓冲器。
Basing on rheological dynamics,a damper with sealed clearance type of annular gap structure is applied to a landing gear and analyzed.Its mechanical model is established based on the Bingham model and forces exerted on the damper are simplified.Numerical simulation results show that the mechanical model of the damper presented here can reflect the dynamic characteristics of the landing gear damper and is applicable for the landing gear damper.
