Research on Modular Modeling Method of Vehicle Driveline System

In this paper, the standard transmission matrix of the key component in the driveline was established, and connection method of basic modular transmission matrix was built based on the correlation characteristics of the degree of freedom between the modular, and the modular modeling method was proposed base on the transmission characteristics of the key component in the driveline. The modular modeling method was verified with test data. And the modular modeling and analysis process of the vehicle driveline system was coded, and the vehicle driveline system module management system was developed with Visual Basic, which can realize the function of hierarchical management of the key components in the vehicle driveline system, configuration of the driveline system and calculation of the system dynamic characteristics. The study can provide a technical template and theoretical basis for the establishment and analysis of the dynamic model of the vehicle driveline system.
