Monitoring of Particle Mass Flow Rate in Pneumatic Conveying Based on Acoustic Emission
摘要
Abstract
The particle mass flow rate in pneumatic conveying is one of the important parameters to be monitored during the operation.The real time on-line measurement can be realized by using the acoustic emission signals to monitoring the particle mass flow rate.In this paper,by using the Ensemble Empirical Mode Decomposition(EEMD)algorithm,which can decompose the signals based on the original signal,and the artificial neural network,which has the excellent nonlinear mapping ability, an EEMD and BP neural network combined mass flow measurement model is established. The experimental data samples are used to train the network to achieve the mass flow online estimation.It is found that result of the joint model is in good agreement with the experimental result.This work provides a simple and reliable method for the on-line measurement of particle mass rate flow in pneumatic conveying.关键词
