Research On Key Technologies Of Data Management Of Cae For Railway Freight Car

CAE-based simulation analysis is used more and more widely and deeply in the design of railway freight cars, which introduces a large number of data in the simulation analysis of railway freight cars, such as various types of simulation analysis of the pre-processing, post-processing, calculation framework, grid model, etc. and so on. However, due to the large variation, complicated structure and special characteristics of the data, the current management for the data is still of many problems, mainly reflected as follows: data storage scattered, poor reuse, the lack of and application of integration, does not support collaborative design and simulation analysis, and so on. To solve the problems above,"Data Management System of CAE for Railway Freight Car"is proposed by our group, combined with the characteristics of simulation analysis of railway freight cars, the framework of the system is given, mainly about simulation task management, simulation model data management, processes management of simulation.Based on those key technologies, related modules of the system are developed. The research contents of this thesis are given as follows:Firstly, the research of Collaborative Simulation Management technology is analysed, combined with the status and functional requirements of the wagon industry, and the overall framework and functional systems of the wagon simulation data management system is provided.Secondly, based on the overall structure of the wagon simulation data management system and the data organization and management mechanisms, the key technologies of the system are studied.These techniques include simulation task management, simulation process control, simulation model data management, organization and competence of personnel management. And now the system can manage the data of the whole process on simulation.Finally, a prototype system was developed based on .NET framework. Through the implementation in a wagon manufacturing enterprise in Qiqihar, the result indicated that the system can effectively manage and reuse of simulation data, increasing R & D capability of enterprises.
