The friction wedge is a critical component in the three-piece truck. This paper describes the current approach for modeling friction wedges and compares its implementation in the commercially available NUCARS™ and VAMPIRE® vehicle dynamics codes. NUCARS™ is a software package developed by Transportation Technology Center, Inc., while VAMPIRE® is a package developed by AEA Technology plc. Sample results from both codes are presented based on standalone test cases. Shortcomings of the “state-of-the-art” model are described and directions for future work are proposed.
