摘　　要：飞机控制广泛使用液压传动系统,在控制面操纵过程中,会造成液压系统内压力变动,对液压管路产生一定的冲击,液压管路在冲击下会产生变形和振动,进而影响管路内液体流动,产生流固耦合现象。本文对某液压管的流固耦合现象进行了CFD/CSD数值计算,得到了液压管内流动特性以及管壁的结构动响应,为液压管路的设计提供数值参考。Hydraulic transmission system is widely used in aircraft controls.During the operation of the control surface,pressure fluctuations in the hydraulic system can cause certain impacts on the hydraulic pipelines.The hydraulic pipelines may deform and vibrate due to these impacts,affecting the flow of liquid in the pipelines which fluid solid coupling phenomena comes into being.This article introduces CFD/CSD numerical calculations on the fluid solid coupling phenomena of a hydraulic pipe so as to obtain the flow characteristics inside the hydraulic pipe and the structural dynamic response of the pipe wall,providing numerical reference for the design of hydraulic pipelines.
