Construction method of virtual prototype of multi-axle heavy vehicle

Abstract

The construction method of the multi-axle heavy-duty vehicle virtual prototype of the present invention uses ADAMS as the application software platform, uses Matlab as the application realization tool, and uses the cmd script language and the m language as the development language to develop and form parameterized and modularized model templates and parameter templates Four types of templates, function module templates, and model binding templates, and two types of application services, parameter analysis and model binding, realize rapid construction of dynamic models through file packaging and batch processing operations. The construction method of the virtual prototype of the multi-axle heavy vehicle of the present invention realizes the parameterization and templateization of the main functional modules of the multi-axle heavy vehicle, and the vehicle dynamics model is constructed with templates and parameters as the core, realizing the explicitization of enterprise tacit knowledge, Streamlined, improving work efficiency and repeatability of the work process; significantly improving modeling efficiency, while supporting parameter-based product optimization and sensitivity analysis.

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 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 provide 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 features, and does not support automatic model construction and model reuse. Some virtual prototypes adopt the m...
