VEHICLE DATA PACKAGE FOR
DYNAMIC SYSTEM MODELING AND SIMULATION
1.0 INTRODUCTION
This package describes the parametric data requirements for high resolution vehicle propulsion systems analysis. The nature of these methodologies is such that detailed vehicle data is necessary to formulate the models for the simulation to be performed. In order to facilitate the development of propulsion system models of modern military vehicle systems, an attempt has been made here to provide generic data sheets to define the system parameters necessary to conduct any desired simulations. These sheets include the minimal requirements necessary to conduct simulations. Special features or performance characteristics which are not covered by the data sheets need to be described and parameters provided in sufficient detail for high resolution simulations.
2.0 OBJECTIVES
The purpose of this package is to: 1) define in detail the parameters, and descriptions that are necessary to perform high resolution vehicle models using simulation methodologies and 2) provide standardized work sheets which will facilitate vehicle system description and model development.
3.0 RECOMMENDATIONS
As the government deems it necessary, this package will be updated to add data requirements as modeling methodologies and simulation technologies advance.
4.0 DISCUSSION
In order to determine the dynamic response of wheeled vehicles, parametric data that describes the main subsystems of the vehicle must be known. The following data sheets are included to capture that data.
