Method and device for instantiating structure tree of high-speed train

The embodiment of the invention discloses a method for instantiating a structure tree of a high-speed train. The method comprises acquiring the hierarchical data and the structural topological data of a known high-speed train model; according to the hierarchical data and the structural topological data of the known high-speed train model, constructing and saving a structure tree instance of the known model; calling the structure tree instance of the known model as an initial design structure tree and presenting the initial design structure tree when it is required to instantiate a structure tree of a new developed high-speed train model; providing a dynamic management tool in response to a modification request for the initial design structure tree; in response to the operation executed through the dynamic management tool according to a technical index of the new developed high-speed train model, adding and/or deleting a structural unit on the initial design structure tree in order to obtain and present a target design structural tree; and in response to the confirmation operation to the target design structural tree, saving the target design structural tree as a structural tree instance of the new developed high-speed train model.
