Rapid Rail Vehicles Curved Door Design Technology Research And System Development,

Rapid design has been proposed and developed owing to the demand of products diversity and rapid update, and it refers to all the design techniques and methods in aid of shortening the cycle of product development. Rapid design involves all kinds of advanced design technology including modularization, parameterization, finite element analysis and the design tool based on CAD.Firstly, on the basis of fundamental method of rapid design, the rapid design method is put forward in this paper, which combines finite element analysis with modularization and parameterization in SolidWorks platforms.Secondly, modularization technique is used in the structure analysis of product. The modeling means using mainly top-down modeling and subsidiarily down-top modeling is applied, and controlling codes are programmed through applying API and VBA in SolidWorks. The product is detected by finite element technique.Finally, the rapid design system is developed for bend door of railway vehicles, and it has got an effective application in enterprises.The rapid design system generate the products according to the need of customers in order to get rapid prototyping and market lead time. It not only reduces time of project development and its cost, but also strengthens the communication ability among all the departments.
