Development Of A Recording Volumetric Transducer For Studying Effects Of Soil Parameters On Compaction, J. D. Hovanesian, Wesley F. Buchele Jan 1959

Development Of A Recording Volumetric Transducer For Studying Effects Of Soil Parameters On Compaction, J. D. Hovanesian, Wesley F. Buchele

Wesley F. Buchele

Increased research effort has been directed toward the solution of soil compaction problems in the past few years. Research workers dealing with these problems have been handicapped for at least the following four reasons: 1 Lack of definition and understand­ing of soil stress and soil compaction; a need for a suitable mathematical model 2 Lack of suitable recording equip­ment for measuring changes in soil physical phenomena, particularly soil compaction 3 Lack of basic engineering infor­mation about the mechanics of agri­cultural soils 4 Lack of adequate information showing the effect of certain parameters (soil moisture, soil type ...


Design And Operation Of The Msu Tandem Tractor, Wesley F. Buchele Jan 1959

Design And Operation Of The Msu Tandem Tractor, Wesley F. Buchele

Wesley F. Buchele

A tandem tractor composed of two tractors hooked together and con­trolled from the rear tractor has been built at the Agricultural Engineering Department, Michigan State University. It was tested on sod, plowed, and plowed and disked land. Results indi­cate that the tandem tractor can pro­vide the farmer with a versatile power unit: one four-wheel drive tractor for pulling heavy loads; and two two-wheel drive tractors for pulling light loads.


Application Of Continuum Mechanics To Soil Compaction, G. E. Vandenberg, Wesley F. Buchele, L. E. Malvern Jan 1958

Application Of Continuum Mechanics To Soil Compaction, G. E. Vandenberg, Wesley F. Buchele, L. E. Malvern

Wesley F. Buchele

To study the soil compaction prob­lem, the amount of compaction change at every point in the soil resulting from loads applied to the surface must be de­termined. If this change can be calculated, the effects obtained from varying the loads can be observed and thereby information gained which will permit predicting and possibly controlling compaction. Such cal­culations require a suitable theory of soil mechanics to formulate a mathematical model describing the soil.
