Software Integration for Simulation-Based Analysis and Robust Design Automation of HMMWV Rollover Behavior

摘要

A multi-body dynamics model of the U.S. Army's High Mobility Multi- purpose Wheeled Vehicle (HMMWV) has been created using commercial software (ADAMS) to simulate and analyze the vehicle's rollover behavior. However, manual operation of such simulation and analysis for design purposes is prohibitively expensive and time consuming, limiting the engineers' ability to utilize the model fully and extract from it useful design information in a timely, cost-effective manner. To address this challenge, a commercial system integration and optimization software (OPTIMUS) is utilized in order to automate the simulation processes and to enable the more complex uncertainty- based analysis of the HMMWV rollover behavior under a variety of external conditions. Challenges involved in integrating the software are highlighted and remedies are discussed. Rollover analysis results from using the integrated model and automated simulation are also presented. The results offer important information and design insights that would have been very difficult to obtain without the automation provided by the integrated software.
