Abstract: Heated mandrel winding is a new method which can achieve composite shell efficient winding. The temperature uniformity of heated mandrel surface is a very significant factor which influences the quality of the composite shell. In this paper, we select heated mandrel as the research object and take the location of mandrel little hole as the optimization variable. We design three factors three levels of test scheme based on Box-Behnken design methods. Then, based on this scheme, Fluent numerical simulation was carried out. Setting temperature trace points on mandrel and writing down the temperature value of these trace points, we calculate the temperature mean square error (MSE) and take MSE values as the response value. By fitting second order response surface equation, using statistical software Minitab to analyze the best position combination, and eventually, following the best scheme to do Fluent simulation, the results showed that model predicted values were in good agreements with simulation values. The temperature MSE of mandrel surface is only 1.96K and the temperature uniformity is good.
