The U.S. Army Tank Automotive Research, Development, and Engineering Center TARDEC desires to increase the fuel efficiency of its ground vehicle fleet. A stationary axle test stand has been designed and built in an effort to create a method of determining axle efficiency as a function of the lubricating fluid used. It has been designed based on operating conditions required to replicate a pre-defined transient driving cycle for the tactical wheeled vehicles representing light, medium, and heavy duty equipment. Preliminary repeatability data has been established, and technical investigations and improvements to the test stand have been developed for follow on work. An industry survey of fuel efficient gear oils was also conducted to support overall Army fuel efficient gear oil research.
