The rail transit vehicle window frame comprises a window frame body, a roller shutter assembly, a mounting plate and a hook are arranged on the window frame body, and the window frame body comprises a window plate and a window frame side wall plate integrally formed along the periphery of the window plate. The window is characterized in that the window frame is formed by curing multiple layers of composite material prepregs, aramid fiber honeycomb sandwich layers are laid in the multiple layers of composite material prepregs at the corresponding positions of the window frame side wall plate and the window plate, and metal pieces used for installing the roller shutter assembly, the installation plate and the hook are pre-buried in the window frame. The flame-retardant window frame has excellent flame-retardant performance and is suitable for large-area integral forming, so that the window frame has the advantages of light weight, high strength, fire prevention, environmental protection, sound insulation and heat insulation, the installation reliability and safety are higher, and the service life is longer. The invention further provides a design method of the rail transit vehicle window frame.
