Structure Optimization for Backrest frame of CRH Seat Based on DOE Analysis
The stiffness of the seat from CRH high speed train was studied.First,FEM analysis was performed on the entire seat and the backrest frame.Results showed that the backrest frame accounts for most of the seats deformation.Then a three factors and three levels orthogonal experiment was designed to find which component affects the stiffness of backrest.From the results of nine experiments,conclusion that side beams have the high sensitivity on seat stiffness.Finally,size optimization was carried on to find best cross section of the side beam.The FEM analysis of new design showed that the maximum deformation of the seat was 9.27mm,decreased by 24.1% compared with original design
