Abstract:
In this scientific paper we
presented a soil- tool interaction testing
device, which was projected, built,
instrumented and evaluated. This soil bin
has been designed to study on the soil−tool
interaction. It features a 23-m long by 2 -m
wide by 1-m deep. An electric drive system
was used to pull a carriage by two chains.
The carriage has a capacity of testing three
prototypes of tools at each run. The testing
tools on the moving carriage are pulled or
pushed in the soil channel through a chain
drive system. Respective transducers were
positioned at various localities interfaced to
a data acquisition system to measure and
save the various measurement parameters
such as forces, speed, moments and
displacements. The system of data
acquisition was able to receive the measured
signals in real time, display on the monitor
screen and record them into a computer. The
performance of the testing facility was
evaluated and validated during some initial
tests.
