A pre-processing template and processing method for a high-speed vehicle simulation model

Abstract

Disclosed are a pre-processing template and processing method for a simulation model of a high speed driving vehicle. The pre-processing template comprises a simulation model to be processed, a working condition definition module, a naming standardisation and curved surface processing module, a grid processing module and a boundary condition module. The working condition definition module is used for determining various working conditions of a running state of the simulation model to be processed. The naming standardisation and curved surface processing module comprises a surface processing module and a name setting module. The surface processing module is used for smoothing the surface of the simulation model to be processed. The name setting module is used for performing curved surface division on the smoothed simulation model according to a curved surface division rule, and name divided curved surfaces. The grid processing module establishes different grid processing procedures according to different working conditions, and performs simulated analysis on the running state of a simulated vehicle. The template and method can simplify complicated pre-processing operations in simulated analysis, thereby improving the working efficiency and reducing human errors.

Problems solved by technology

[0004] Therefore, more and more simulation models based on fluid mechanics are applied to train design, and the establishment of a simulation model based on fluid mechanics is mainly to establish a mathematical model of fluid mechanics, which not only includes the discretization and solution methods of mathematical equations, but also Including the establishment of computational grids and the processing of boundary conditions. Therefore, the pre-processing template of the high-speed vehicle simulation model is mainly to complete the establishment of computational domain grids and the processing of boundary conditions. Due to the professional complexity of subject simulation, various The simulation analysis software is scattered in various majors and operated by a small number of design and simulation personnel. Knowledge and experience are scattered among individuals, making it difficult to accumulate and share, which is not conducive to the accumulation of enterprise knowledge and the formation of expert knowledge base. At the same time, facing complex simulation analysis objects, it is necessary to have Standard method to help designers quickly understand the analysis process steps, quickly complete tedious parameter input, complex working condition definition and simulation report generation, and accumulate and share simulation knowledge and experience
