Computer Simulation of a Hydrostatic Drive for a Soil Bin

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">An analysis has been conducted on the hydrostatic drive system for driving a soil bin. A comparison of the bin velocity was made between the pure inertia load and inertia plus disturbance. Also, the pressure fluctuations that are predicted are quite sensitive to the leakage values chosen.

Soil Bin Scale-Model Testing

SAE Technical Paper Series, 1969
<div class="htmlview paragraph">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 ...

Soil Bin and Field Tests of an On-The-Go Soil Strength Profile Sensor

Transactions of the ASABE, 2008
An on-the-go soil strength profile sensor (SSPS) was previously developed to measure the within-field spatial variability in soil strength at five evenly spaced depths up to 50 cm. In this article, performance of the SSPS was evaluated using soil bin and field data.

Experimental evaluation of cutting dynamic models in soil bin facility

Journal of Terramechanics, 1992
Computer Aided Engineering methods in earthmoving machines design and their automation require the developrnent of soil cutting models. These models both in two or three dimension, static or dynamic, fitted for frictional and cohesive soils, must be mutually compatible and must accomplish with soil transportation models and with machine locomotion ...

Dynamic Performance of Drill Coulters in a Soil Bin

Journal of Agricultural Engineering Research, 1999
Abstract A laboratory experiment was conducted to examine the vertical movement of two different conventional drill coulters in a soil bin. The bin was filled with air-dried sand, and was configured without straw, and with a surface covering of straw of two different length distributions. The objective of the experiment was to compare the movement of

Soil-Blade Interaction of a Rotary Tiller: Soil Bin Evaluation

International Journal of Sustainable Agricultural Research, 2014
In this paper soil-blade investigation of a rotary tiller in a controlled soil bin is presented. Among the soil cutting agricultural tools currently used, the rotary tiller is one of the most promising equipment, saving operating time and labor. In a rotary tiller working tool is always a blade.

An Explosive Subsoiler for the Improvement of Meadow Soil, Part 2: Soil Bin Experiments

Journal of Agricultural Engineering Research, 2000
Abstract An explosive subsoiler was envisaged and designed to achieve greater soil rupture volume and longer sustainability of drainage for the improvement of meadow soil. In this paper, the results are presented from soil bin experiments with the explosive subsoiler, that were conducted in Japan prior to field experiments in China, to investigate ...

Innovative Design Features of A Soil Bin to Facilitate Research on Soil-Tool Interaction

2002 Chicago, IL July 28-31, 2002, 2002
A soil bin test facility has been designed to study on soil-tool interaction. It features a 20-m long by 2.44-m wide by 1-m deep bin, which supports eight segmented soil boxes. Soil conditions can be changed by inserting replacement soil box. The bin can be inclined up to the maximum slope grade of 20%.

Energy Evaluation of Tillage Tools Using Soil Bin

SAE Technical Paper Series, 1991
<div class="htmlview paragraph">Tillage is an importantcomponent of crop production system and may be defined as any mechanical manipulation of soil to improve its appearance and physical condition for crop production. The factors affecting the energy requirement by a tillage tools include initial soil conditions, tool shape, and manner of tool ...
