An Application of Genetic Algorithm to Multiparameter Optimization of Lateral Stability in Railway Passenger Train

Genetic algorithm is used to carry out the parameter optimization of lateral stability in railway passenger train. The optimal model is a typical dynamic one of railway passenger train and object function is the maximal permitted running speed of the train. The result indicates that genetic algorithm holds better suitability in solving parameter optimization problem of vehicle dynamic system. This method offers the possibility of getting wholly optimal result,particularly to the nonlinear problem with multiparameter and multi peak function.
