Soil Bin Scale-Model Testing 690357

The new soil bin facilities at the Earthmoving Equipment Division of General Motors are described. Fundamental values of soil bin scale-model testing are discussed. One of the major values of soil bin scale-model testing is the reliable prediction of vehicle performance by “scaling-up” of the soil bin scale-model data. Recent studies in the Engineering Research Group at the Earthmoving Equipment Division of General Motors have shown that scraper model and full-size loading force correlations can be made, and that crawler tractor model and full-size drawbar force correlations can be also made.
