摘　　要：本文针对绳系并联支撑系统在低速风洞中的应用,对流场引起的牵引绳振动情况进行了流固耦合分析。基于ANSYS workbench的流固耦合模块,对来流速度为17 m/s时绳的振动特性进行分析。首先通过单向流固耦合分析,选择牵引绳最佳预紧力。其次,利用双向流固耦合模块,分析了不同工况下绳的振动特性,给出了对应情况下绳的最大振动位移点及其历程变化。结果表明,最大振动位移点基本都在绳中间位置,且振动位移较小;绳最大振动方向主要表现为顺流向,不同工况对绳的振动行为会有一定影响,但影响较小。According to the application of cable-driven parallel manipulator (CDPM) in a low-speed wind tunnel, fluid-structure interaction analysis of cable induced vibration caused by the incoming flow is presented in this paper. The vibration characteristic of a cable with the airspeed of 17 m/s is analyzed using the fluid-structure interaction module of ANSYS workbench. The optimal pre-tension of cable is determined through the unilateral fluid-structure interaction analysis. Then the vibration characteristics of a cable under different conditions are simulated with bidirectional fluid-structure interaction module, and the maximum vibration displacement point with corresponding change history under different vibration conditions is given. The simulation results show that the maximum vibration displacement point locates at the middle of the cable and the vibration displacement is small. The maximum vibration direction is the same as the direction of the wind. Different operating conditions have influence on the vibration of cable, but the influence is relatively small.
