叶片式抛送装置功耗试验研究与参数优化
Parameter optimization and experiment for the power consumption of impeller-blower
摘要
Abstract
In order to improve the quality of whole straw coverage with no tillage planter and reduce the throwing power consumption.Box-Benhnken central composite experimental design principle was adopted to study the working parameters of impeller-blower.Rotating speed,material moisture,vane slope angle were taken as three factors.Experiments on the three factors with three levels of response surface were conducted.A mathematical model of response surface was established.The influence of each factor on the working quality and optimize each factor comprehensively was analyzed.The results showed that the rotating speed,material moisture,vane slope angle in a decreasing order reduced power consumption significantly.The best model for comprehensive work parameters was set as following:when the rotating speed was 1 600 r/min,the material moisture was 63％ and vane slope angle was 9°,the specific power consumption was 919.89 m2/s2.Through comparing the mathematical model with the experimental result,it was discovered that the relative errors of all the property indices between these two were less than 5％ indicating the model established was useful and could be used for predicting and optimizing.关键词
