Mobility Exercise A (MEXA) Field Test Program, Report 2. Performance of MEXA and Three Military Vehicles in Soft Soil. Volume 1

Abstract

In the concept phase of Mobility Exercise A (MEXA) the principal purpose was to design vehicles capable of operating in remote areas of the world where extremely soft soils predominate, and to develop a program of tests for evaluating these vehicles in soft soils. As a result of the MEXA concept phase, two 2-1/2-ton wheeled and one 2-1/2-ton tracked vehicles were designed. After the MEXA vehicles were fabricated, a field test program was designed and conducted. A total of 328 tests were conducted on level clay soils. The purpose of the test program was to evaluate the performance of the three MEXA vehicles (MEXA 10x10, MEXA 8x8, and MEXA track) and three military vehicles (XM410E1, M35A2 (mod), and M113) on a range of soil strengths and to compare the measured and the predicted performances of the vehicles. Test results indicate that the MEXA vehicles do what they were designed to do, i.e. perform better on soft soils than military vehicles. However, on firm soil and on pavement, performance is not as good as that of the military vehicles.
