| 摘 要： | 为了分析复杂流场对叶片的作用,研究了压气机内三种非定常气动激振形式:上游叶片排尾迹、进气畸变和旋转失速的相关性.通过在单级低速轴流压气机试验台上获得的数据,采用自相关和互相关方法,研究三种激励的特性,分析激振信号的相关性机理.结果表明:多次自相关可以清晰地显示出信号的特征频率,有效地抑制干扰噪声;激励信号之间具有很强的...

| Abstract: | The correlation of the three excitation forms(up-stream blade rows wakes,inlet distortion and rotating stall)was studied to analyze complex flow field of the blade role.The experimental samples were obtained by a single-stage low speed axial compressor test rig.Research focused on analysis of these three types of periodical excitation,employed autocorrelation and cross-correlation approach.Experimental results show that there is high correlation between excitation signals,and the correlation degree rely hea... |
