Study On Parameters Of Self-Excited Pulse Jet Device Based On Orthogonal Test

On the basis of the serious problem of the current reservoir and river sedimentation in China,In this paper,the method of orthogonal experiment is used to study the application of self-excited inspiratory pulse jet in reservoir dredging.This paper starts with the operating parameters and structural parameters of the device which can affecting device performance,Firstly,the orthogonal test and analysis of the single type parameters between the operating parameters or the structural parameters are carried out.Then the orthogonal test and analysis of all kinds of parameters of operating parameters and structural parameters are carried out.The paper introduces the background and significance of this study at first.Then on the basis of a large number of domestic and foreign literature,the research situation,mechanism,frequency performance,inspiratory performance,pulse performance and application of self-excited pulsed jet are introduced.T Then the orthogonal test method and the method of constructing orthogonal table are introduced.In this paper,the influence of parameters on the performance of the self-excited pulse jet device is studied by orthogonal experiments.Firstly,the structural parameters of the device were tested by orthogonal test.Then the orthogonal test of the operating parameters of the device was carried out.Finally,the orthogonal experimental study on the structural parameters and operating parameters is carried out.In the paper,the influence of the parameters and the interaction between the parameters on the performance of the device is studied.The paper rank each factor according to the importance of influence for device performance,then analysis of the interaction between the various factors.Finally,the paper summarizes the full text and puts forward the prospect of future research.
