OPTIMIZATION DESIGN OF EXHAUST MANIFOLD BASED ON FACE-TO-HEART COMBINATION OF RESPONSE SURFACE METHOD
In order to solve the limitations caused by the engine exhaust manifold structure optimization which usually adopts single factor control variable method or orthogonal test leading to the insignificant parameter interaction,the face centered combination method in the central composite design is used...

| description | In order to solve the limitations caused by the engine exhaust manifold structure optimization which usually adopts single factor control variable method or orthogonal test leading to the insignificant parameter interaction,the face centered combination method in the central composite design is used to respond to surface optimization,taking the engine exhaust manifold of a heavy chemical vehicle as the research object,the exhaust 38 groups of manifold structural parameters finish the fast matching,the mathematical model is established and polynomial response regression equation is concluded,fitting out of the exhaust manifold optimum structural parameters and corresponding flow uniformity index,additionally,the results of response surface optimization is verified by the numerical simulation.The results show that when the four branches are combined,the optimal structure fluid flow uniformity index of the exhaust manifold by the response surface method based on the face centered combination way is improved from the original 0.76 to 0.82,which is 6% higher than the initial structure. |
