Abstract

The invention provides a method and system for multi-body model form control. The method comprises the steps of reading a form file comprising controllable model parameters; obtaining a subsystem configuring file selected by a user and writing the model parameter information in the read form file to a new subsystem file needing to be configured; and generating a new assembly file by utilizing preset data information and the subsystem file, storing the new generated subsystem file and assembly file under a set path and copying a needed template file and other property files to the set path so as to generate a full vehicle model database for simulating calculation. By utilizing the method, the model parameter-updated subsystem file, the assembly file and a database folder containing all the needed files can be automatically generated; the database can be directly used for simulation without referencing other files; the whole model generating process is automatically completed by the system; and therefore, the obtaining is quicker and more accurate.

Description

technical field [0001] The invention relates to tabular modeling of multi-body dynamic models, in particular to a method and system for tabular management and control of multi-body models. Background technique [0002] In the development process of vehicle models, the multi-body system modeling software Adams (Automatic Dynamic Analysis of Mechanical Systems, automatic analysis of mechanical system dynamics) has been widely used, especially the use of Adams / Car is the most important. In the traditional usage method, Adams adopts a 3D-based visual modeling method, which is suitable for initial development from scratch. However, when a large number of model parameters need to be adjusted after the structural form of the product model is determined, the traditional visual modeling method is not suitable for the low efficiency because it cannot process the parameters in batches. [0003] A complete Adams / Car model that can be used for simulation calculation is a database folder...
