摘要
基于分形理论 ,提出了流体机械轴心轨迹稳定性的定量评价指标。实际应用表明 ,该指标较好地反映了转子运行稳定性的实际状况 。
Based on fractal theory, the index to evaluate the running stability of fluid machine is put forward. It is shown that this index truely reflected the actual operating condition in practice .The effective means for quantitively moniyoring rotor's running stability is provided.
