摘　　要：喘振现象是压气机部件较为常见的故障之一,工程中经常采用可调静子叶片(VSV)调节机构改变叶片角度进而预防喘振现象的发生。为明确可调静子叶片调节机构的运行特性,满足可调静子叶片调节机构在运行过程中运行特性要求,依托某型航空发动机设计搭建了VSV机构运动特性试验台,在不同速度下开展了VSV机构阻力专项验证试验,分别得到了不同配合间隙衬套叶片转动角度数据和不同速度工况下调节机构阻力数据。试验结果表明:叶片角度随行程变化曲线在下降行程中的波动更加明显;叶片级数越高,转动角度范围越小,S0与S4级叶片转动角度分别保持在30°与3°附近;在下降行程阶段驱动力幅值减小且保持较为平稳状态,机构阻滞力在驱动上升和下降行程中存在阶跃现象,S1级下降行程阶跃现象表现更明显,上升行程阻滞力约为-400 N,而下降行程可达-450 N。Surge phenomenon is one of the common faults in compressor components.The adjusting mechanism of variable stator vane(VSV)is often used to change the angle and prevent the occurrence of surge phenomenon in engineering.To determine the operating characteristics of the adjusting mechanism of VSV and meet the operating charateristics requirements in the operating process,a test rig for the oper-ating characteristics of the VSV mechanism was designed and built based on a certain type of aero-en-gine.A dedicated verification test of resistive force of the VSV mechanism at different speeds was carried out,and the blade rotation angle data under different tolerance clearance bushing conditions and the ad-justing mechanism resistance force data at different speeds were obtained.The test results show that the fluctuation of the blade angle variation curve in descending stroke is more obvious;the higher number of blade stages,the smaller the range of the rotation angle,and the rotation angles of the S0 and S4 stage blades are kept near 30°and 3°,respectively.And the amplitude of driving force decreases and remains relatively stable in descending stroke.The step phenomenon of mechanism resistive force occurs during the ascending and descending strokes of the actuator cylinder.The step phenomenon of S1 stage in de-scending stroke is more obvious,the resistive force in ascending stroke is about-400 N,and that in the descending stroke can reach-450 N.
