On the basis of the response surface model theory,the finite element numerical simulation method is used to analyze the temperature distribution of the barn in winter and summer,respectively.A temperature inversion mathematical model of large barn is obtained.According to the single factor rotation method,orthogonal experiments and statistical methods,the collected multi-points temperature are put into response surface model to construct a polynomial.This polynomial is used to predict the inverse mathematical model of temperature distribution in the granary.The design space,the main effect and interactive effect which are affected by the interaction of each factor are given.Experimental results show that the model has high precision,small error rate and good computing performance.In large barn,it can solve the problem of less wiring and temperature forecasting in wide space by using this model. |
