Results Derived from Soil-Vehicle Field Test Program of MEXA Design Vehicles

The results of field tests of MEXA two wheeled and one tracked vehicles on soft-soil terrain and evaluation of vehicle performance are described in this paper.

Design criteria are presented, and the systems used to meet these criteria-AMRB Mobility Index System, AMRB Numeric System for wheeled vehicles, and LLL Soil Value System-are described.

Test sites and procedure are also described, and VCI test results are detailed. Experimental test results of the MEXA vehicles are compared with the design criteria and predicted performance of the actual vehicles. Speed test results are also discussed, as is the performance of MEXA vehicles, articulated steering, and inching systems in soft soils.
