Title: Study on model establishment method in digital primitive model bank belong to maintenance department
Abstract: The digital track maintenance program has created a virtual environment that stands imperative to digital railway. The construction of an element bank dedicated to this area may ease the recreation of the track structure,which further simplifies the working flow in building up the virtual environment for digital track maintenance. In this sense,the paper proposes the parameterized 3D modeling method for the construction of simple model elements,and suggests the use of AutoCAD and 3DS MAX software in case of complicated elements. Accordingly,an in-depth study is conducted to work out a simplified calculation approach. The heterogeneous origin of the model gives inspirations to a compatible interface for the model reading and the solutions to the Oracle database storage. At the same time,the paper,with the help of the digital route-selection system and the HSR digital simulation system,studies the construction methods of the virtual environment and its working effect. The results indicate that the application of the element database effectively trim the construction flow of the environment.
