Abstract: The
objective of this study was to computational analysis and comparison of a new
graphical method of moldboard plough bottom design with previous graphical
methods. Results show that the new method made the design and manufacturing
process of plough bottom simpler. Also, this method decreased the weight of the
bottom up to 7.3% due to the reduction of the overdesigned surface of it up to
273.5 cm2. Therefore, based on this developed method, the price and
magnitude of energy consumption of the moldboard plough decreases due to reduce
of the weight of bottom and its friction with soil. Also, a three dimensional
model of the new designed bottom was designed using CATIA V5R16. Then, computational
simulation of the bottom was carried out by ABAQUS V6.9 utilizing the finite
element method. Interactions between the bottom and the test soil (sandy loam)
were applied to the simulation using a distributed load applied to the surface
of moldboard and share. This distributed load was obtained from interpolation
among 14 point forces measured from field tests using piezo-resistive
transducers located on the working surface of the bottom. The load distribution
was then derived by using spatial interpolation. Results show that this new
designed bottom can easily withstand the applied stresses and displacements
during plowing process. Results obtained from this study are suitable for the
manufacturers of moldboard plough specially those who wish to use the finite
element method to improve their products.
