| Abstract: | A design strategy based on optimization is developed in this paper to solve the comprehensive design problem for high-speed railway passenger vehicles.It tries to design the lightweight car body structure with multi-level optimization and analyses,which may satisfy the requirements of both elastic deformations in all ordinary conditions and plastic deformations in crash events.A concept model of railway vehicle and high-speed passenger vehicle were studied to execute the design procedure suggested by using linear and non-linear finite element techniques.The results of numerical analyses has proved its feasibility and effectiveness. |
