  • In urban rail transit, evacuation platform is a necessary safety passage which can ensure the rapid and orderly evacuation of passengers from the tunnel to the safety area as soon as possible in the case of train failure or other abnormal conditions. Composite materials of light weight, high strength, strong designability and fire prevention have been gradually applied to evacuation platform. In view of the continuous improvement of the lightweight requirements for composite materials in engineering applications, the purpose of reducing the structural weight is achieved on the basis of meeting the material strength and structural deformation. In this study, the deformation and strength of the existing composite evacuation platform are analyzed, and optimization variables are defined. With its mass, strength and overall deformation as the objective function and the multi-objective optimization based on response surface method idea, the function relationship between the objective function and the optimization index is discussed. The appropriate solution is obtained by comparison, and the selected solution is further verified.Resultsshow that when the strength and the overall deformation of the optimized evacuation platform are guaranteed, its weight decreases.
