Abstract：Aiming at the problem of lightweight design of door-leaf carrier of EMU sliding plug door,based on the finite element analysis and parametric articles of door-leaf carrier,the radial basis function was used for an approximate model based on the radical basis function was constructed.Then by combining the global superiority of multi-island genetic algorithm and the high efficiency of NIPQL approximate model was optimized.The strengh check results showed that the total weight of the door-leaf carrier was 11.356 kg,decreased by 10.6％,the maximum stress under three working condition was 93 MPa,which satisfied stree requirement.This lighweigh design was suitable.
