PURPOSE: An automatic structure analyzing method of railroad cars is provided to reduce costs and time by performing the structure analysis and design verification of car body design. CONSTITUTION: If a car body shape is selected from database which stores a body shape of a user definition model and a railroad car body shape and a numerical specification of the body shape is inputted through user input(S100). The body shape designed by the specification is calculated(S200). The structure analysis for the car body is performed(S300). A numerical specification of each part is re-inputted through the user input according to the structure analysis result(S400). An optimization result of the card body shape is calculated by repeating the steps.
