PDM (product data management) connection method and device for rapid design of high-speed train

Abstract

The invention discloses a PDM (product data management) connection method and device for rapid design of a high-speed train. The method comprises steps as follows: a first database of a pedigree scheme design platform is converted into a second database, and a data format in the second database adopts an intermediate format; the second database is converted into a BOM table allowing to be recognized by a PDM system; a solid model is established by use of the BOM table; a unique material number and permission are generated according to the solid model and returned to the pedigree scheme design platform; information of the first database is updated by use of the unique material number and permission; the updated information of the first database is input into a product case model library. By means of the method and the device, the distortion problem of data information transmission between the pedigree design platform and the PDM system of an enterprise can be solved, collaborative operation of subsystems in a follow-up procedure is facilitated, synchronous update of data is realized, and the demands for rapid and efficient research and development of vehicles are met.

Description

technical field [0001] The invention belongs to the technical field of public transport vehicles, in particular to a PDM connection method and device for rapid design of high-speed trains. Background technique [0002] In the development of existing high-speed trains, when the vehicle manufacturer receives the order, it needs to manually decompose the train demand of the order into various component modules, such as load-carrying components, running components, and car body components. The R&D department corresponding to each component designs a vehicle that meets the technical specification requirements based on the demand data and its own design experience. Among them, the demand data includes various types, such as designing 100 second-class seats or 75 first-class seats in a carriage, and the train running speed is greater than 250km / h, which meets the requirements for running in a low temperature environment, etc. In response to the above requirements, R&D personnel ca...
