| Abstract: | Universal performance curve plotting for air motor can be very useful for analyzing per- formance parameters of motors. It is also very conducive to choose reasonable air motor,decrease air consumption and improve work efficiency. Taking advantage of data-handling capacity and graphic capability of MATLAB,multiple linear regression model and BP neural network were in- troduced to process data of experiment bench. Finally, equal-gas consumption curves, external characteristic curve and equip power lines were in good fit in a figure. All these curves can also be used to do air motors＇ performance research. |
