通过计算KDF-5型通风机2个工况下的L-Z复杂度及给出不同工况下复杂度的变化趋势图,得出通风机级间气流脉动信号的复杂性最小,振动信号的复杂度最大并且接近随机系统;噪声的复杂性随流量减小而增大,气流脉动和振动的复杂性随流量减小呈现出先减小后增大的结论。
By calculating the LZ complexity of KDF-5 fan under two operating conditions and giving the change trend of the complexity under different operating conditions, it is concluded that the complexity of the airflow pulsation signal at the fan stage is the least, and the complexity of the vibration signal Maximum and close to the random system; the complexity of the noise increases with the decrease of the flow rate, and the complexity of the air flow pulsation and vibration shows the first decrease and then the increase with the decrease of the flow rate.
