摘要

摘要: 采用数值模拟方法,分析了转、静子轴向间距对转子叶片振动应力的影响.利用CFD程序对进口静叶尾迹作用下的压气机转子叶片排非定常流动进行了数值模拟,并采用所编写的程序将气动载荷转化为有限元模型上的动态压力载荷,进行了结构瞬态响应分析.结果表明:在所考查的轴向间距下,随轴向间距的增大,转子叶片振动应力呈减小趋势,这主要是由于造成压力载荷波动的尾迹强度沿流向是减弱的.

Abstract: The effects of stator-rotor axial spacing on the vibration stress of rotor blade were investigated by numerical simulation method. With use of the CFD program, the unsteady flow of compressor rotor blade row under the action of the wake of the front stator vanes was simulated, then structural dynamic response analysis under loading with the dynamic pressure of finite element model, which was got by interpolation procedures, was presented. Results indicate that under the examined range of axial spacing, the rotor blade vibration stress decreases with the increase of axial spacing because the wake intensity is weakening along the direction of flow, which has a great contribution to the fluctuations of pressure of blade surface.
