摘　　要：立式风洞开展自由失速/尾旋试验要求试验段气流速度具备快速调节能力,阻尼器是实现试验段气流速度快速调节能力的装置。叙述了阻尼器机械结构设计和它的功效,说明了控制系统设计及联调结果,介绍了试验段气流速度快速性调试方法及结论。系统应用表明,风洞试验段气流速度具备一定快速调节能力,具备开展自由失速/尾旋试验条件。The capability of the wind speed quick adjustment is required to develop free stall / spin experiment in vertical wind tunnel test section, which can be realized through the damper. Mechanical construction and efficacy of the damper were presented, design and adjustment of the damper control system were introduced, and debugging means and conclusion were indicated. The results show that it has some quick adjustment capability in Ф5m vertical wind tunnel test section, and it is feasible to develop the free stall/spin experiment in Ф5m vertical wind tunnel.
