| Abstract: | To perform the lightweight design of metro vehicle bogie,according to the international standard UIC 615-4,the main load of bogie frame of a metro vehicle is calculated.Five kinds of extraordinary load conditions are combined by six kinds of load such as vertical load,lateral load,longitudinal load and so on.The weak position of stress is found by finite element strength analysis.The lightweight design of bogie frame is realized by the established optimization model and optimization of OptiStruct,and the total mass of bogie frame is reduced by about 12%. |
