Introduction

The NATO Reference Mobility Model (NRMM) is a simulation tool aimed at predicting the capability of a vehicle to move over specified terrain conditions. NRMM can be used for on-road and cross-country scenarios, it can account for several parameters such as terrain type, moisture content, terrain roughness, vehicle geometry, driver capabilities, etc.

NRMM is traditionally used to facilitate comparison between vehicle design candidates and to assess the mobility of existing vehicles under specific scenarios. The model was originally developed and validated in the USA in the 1970s by the U.S. Army Tank Automotive Research, Development, and Engineering Center (TARDEC) in Warren, Michigan, U.S., and the U.S. Corps of Engineers Waterways Experimental Station (WES) in Vicksburg, Mississippi, U.S.

Four engineers received the 1973 Army R&D Achievement Award for their contribution: Howard Dugoff and Zoltan Janosi from TARDEC and Adam Rula and Cliff Nuttall from WES. The Engineer Research and Development Center (ERDC) remains the code custodian and is responsible for configuration control.

NRMM was revised and updated throughout the years, resulting in the most recent versions, NRMM II users guide published in 1992. NRMM3.0 was released in 2017.

The Next Generation NRMM (NG-NRMM) is currently under development. It will utilize new terramechanics models and advanced computing software. Two videos describing the importance of the NG-NRMM follow:

This NG-NRMM resource page is set up in 3 sections:

  1. **The current NG-NRMM developments including timelines and recent papers and reports.**
  2. **Information on the Cooperative Demonstration of Technology held September 25-27, 2018, at the Keweenaw Research Center in Houghton, MI, USA including 12 presentations and a link to the CDT database.**
  3. **Legacy material related to the development and use of NRMM, NRMM II, and NRMM3.0.**
