The report is concerned with the evaluation of the soft-soil performance of a vehicle concept based on an inclined hemispherical wheel. The performance of the concept was compared to a concept utilizing cylindrical wheels of similar size to the hemispherical wheel and to a conventional vehicle of equal payload capacity currently under development. Tests were conducted to establish the performance of 1/4 scale models of each of the vehicle concepts in the large soil bins located in the Land Locomotion Laboratory. The models were tested in sand and in a sandy loam at three different moisture contents. The models were given code designations and are identified as Concepts A, B, and C. The test results indicate that Concepts B and C have significantly better soft-soil performance than Concept A. The performance of Concept B is equal to that of Concept C. It is concluded that Concept B is equal to that of Concept C. It is concluded that Concept C does not offer any improvement in soft-soil performance and should not be considered as a device to improve mobility on the basis of its soft soil characteristics. The recommendations are that Concept C be given no further consideration for application to military vehicles. (Author)
