vibration flow

On the basis of historical records of maintenance and operation, abnormal vibration of DH air compressor was analyzed using frequency spectrum analysis method. It was found that the rust was washed off from interstage cooler into the flow passage of impeller to cause imbalance.

结合历次检修及运行记录，利用频谱分析方法对DH型空气压缩机的异常振动进行分析，判定出产生振动异常的原因为级间冷却器的锈蚀物冲刷至叶轮流道上造成不平衡。

Based on the principle of flow continuity, the process of tension and compression was simulated and the process of vibration absorption was discussed. Damping characteristics and its main determining factors were analyzed.

根据流量连续性原理，分别对其拉伸和压缩过程进行数值模拟，分析了减振器的阻尼特性，确定其主要影响因素。

The experimental results show that, this improvement can improve the flow of control performance of the system, then improve performance of vibration cutting excavation.

实验结果表明，这种改进能有效地提升流量控制的精确性，实现了对振动掘削性能的改进。
