摘要:

为了减少计算资源消耗并缩短计算时间,获得压缩机转子叶片在周期性非定常气动干涉作用下的叶片表面动应力,创新性地采用剖面边界条件,结合参数设计语言的方法,基于叶片气动载荷的完整映射分布进行了谐响应快速分析,并研究了不同压比、转速下的转子叶片表面动应力。结果表明,通过谐响应快速分析法能准确获取转子叶片表面动应力,叶片表面动应力波动峰值的主导频率为动静干涉频率的倍频,其中以1、2、3倍频为主要频率;随着压比的增加,叶片表面动应力逐渐减小,但主导频率基本不变;随着转速的升高,叶片表面动应力逐渐增大,其主导频率也相应提高。研究结果可为轴流式压缩机在受到周期性动静干涉作用下的转子叶片表面动应力分析提供支持与参考。

Abstract:

In order to obtain the dynamic stress of the compressor rotor blades under periodic unsteady aerodynamic interference with reduced computational resources and time, an innovative method combining sectional boundary conditions with parameter design language was employed. This method enables rapid harmonic response calculations based on a complete mapping of the aerodynamic load distribution on the blades.Using this approach, the dynamic stress on the rotor blade surfaces was analyzed under varying pressure ratios and rotational speeds.The results indicate that the proposed rapid harmonic response method can accurately determine the dynamic stress on rotor blades. The dominant frequencies of the dynamic stress fluctuation peaks are harmonics of the rotor⁃stator interaction frequency, primarily the first, second, and third orders. As the pressure ratio increases, the dynamic stress on the blades gradually decreases, while the dominant frequency remains essentially unchanged; conversely, as the rotational speed increases, the dynamic stress on the blades gradually increases, and the dominant frequency correspondingly increases. The research findings provide support and reference for the analysis of dynamic stress on rotor blades of axial compressors subjected to periodic dynamic⁃static interference.
