Abstract :
Taking multiple parameters of the main structural plates thicknesses and loads as random design variables, the strength reliability of bogie frame is analyzed based on response surface optimization approach and JC method. The response surface optimization approach is used to search the failure points of the structure limit state. Meanwhile, the sensitivity of structure reliability is also analyzed using limit state function that obtained by response surface approach. So that it can offer some useful reference for reliability design of railway vehicle structural strength.
