Study on the Integrated Development System for Carbody of Multiple Unit Based on Digital Prototype Technology
With multiple unit running speed, the carbody structure design, strength and fatigue reliability have become an important part of the multiple unit design. From the design requirements of carbody, based on digital prototype technology, the architecture and the development process of carbody integrated design and simulation platform are put forward. Combined with the process of body design, which includes scheme design, three-dimensional structure design, calculation and verification of strength, fatigue reliability analysis and fatigue life prediction, the main module, the key technologies and methods of the body design and dynamic simulation system are discussed. It has important engineering significance for improving the efficiency of the body design and promoting the carbody design.
