Method for building virtual prototype of multi-shaft heavy vehicle

Abstract

The invention discloses a method for building a virtual prototype of a multi-shaft heavy vehicle. An ADAMS serves as an application software platform, a Matlab serves as an application implementation tool, a cmd scripting language and an m language serve as development languages, four templates such as a parameterized and modularized model template, a parameter template, a functional module template and a model binding template and two application services such as parameter analysis and model binding are formed by development, and a kinetic model can be quickly built by file packaging and batch processing operation. The method for building the virtual prototype of the multi-shaft heavy vehicle has the advantages that the parameterization and the modularization of main functional modules of the multi-shaft heavy vehicle are realized; the kinetic model of the vehicle is built by using the templates and parameters as the core, the domination and the streamlining of tacit enterprise knowledge are realized, and the working efficiency and the repeatability of the working process are improved; the modeling efficiency is remarkably improved, and meanwhile, parameter-based product optimization and sensitivity analysis are supported.

Description

technical field [0001] The invention relates to a method for constructing a virtual prototype of an automobile, in particular to a method for constructing a virtual prototype of a multi-axle heavy-duty vehicle. Background technique [0002] With the development of computer technology and simulation technology, functional virtual prototype has been widely used in complex product design and analysis. The dynamic virtual test prototype construction and simulation analysis based on commercial software and computational multi-body dynamics provides technical means for product design, performance analysis, fault prediction and diagnosis, reliability analysis and other design and analysis. [0003] Although virtual prototyping technology has been used in dynamic system modeling, most of the prototypes are only for a specific model. Virtual prototyping does not have parametric characteristics, and does not support model automatic construction and model reuse. Some virtual prototype...
