USACE Logistics visits CRREL
Third from left is Jeffrey Burbach, director, Directorate of Logistics, Headquarters, USACE, and team representing the USACE Logistics Activity, Millington, Tennessee, who recently visited the U.S. Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory. During their visit Engineering Technician Jesse Stanley provided a briefing on the CRREL Instrumented Vehicle, which is also widely known as the Green Machine. The CIV is based on a 1977 Jeep Cherokee structure that has been equipped with instrumentation to measure three mutually perpendicular forces acting at the interface between the tires and any surface material. In addition, accurate wheel and vehicle speeds and rear axle torque are measured. The vehicle is equipped for front-wheel, rear-wheel or four-wheel drive. A dual brake system allows front-, rear- or four-wheel braking. A minicomputer-based data acquisition system is installed onboard the vehicle to control data collection and to process real-time data.
