1. Title: computer simulation of processes of ripping of
soil and creation of modern engineering for tillage of soil.
2. Aims, objectives and task sharing: reduction of terms
of elaboration and improvement of the quality of created engineering
for tillage of soil at the expense of analysis and intrusion of
world practice of computer simulation of physical processes and
acclimatization them to miscellaneous kinds and conditions of processing
of soil.
3. Project leader: Alexei Chekanovkin.
4. Position: the senior lecturer of stand of strength of
materials and theoretical mechanics, candidate of engineering science.
5. Background and justification for undertaking the project:
the recovery of fertility of soil by its mechanical ripping
always was and will be one of basic elements of agriculture, without
which one obtaining high crops is impossible. The soil is a unique
solid medium. Due to its directional processing such physical conditions
should permanently be restored, which one as much as possible would
meet the requirements the conforming phase of development of cultivated
culture. Therefore always actual the problems on analysis of processes
of tillage of soil, creation and perfecting of miscellaneous means
for processing of soil are. Development of computer technologies,
their response, and also perfecting of the mathematical vehicle
in the field of the numerical methods (in particular, finite element
method), allow by computer simulation fast and qualitatively to
decide such problems. In outcome there is a capability not only
considerably to reduce time and material inputs to creation new
and updating existing is model of engineering for tillage of soil,
but also to improve their technological qualities, reliability of
activity.
6. Term of design complete: 2005-2006 yy.
7. The detail description of the project: In miscellaneous
branches of scientific activity the wide experience of simulation
of processes, bound with physical-mechanical transformations of
soils, specially in building is accumulated. Besides there is an
experience with stuffs, the properties which one come nearer to
properties of soils (bulk materials, dusts, rocks etc.). However
practically there are examples of computer simulation of processes
of machine work of soil, directional on recovery of its fertility.
In this connection it is offered to the interested scientific entities
and separate scientist to aggregate the efforts for implementation
of concrete steps in a direction of usage already known and elaboration
of in essence new computer technologies of simulation and analysis
of recovery processes of physical characteristics of soils as effective
tool, directional on creations of new means for processing of soil.
8. Results, expected to be achieved: As a result of design
complete the techniques of computer simulation of processes of tillage
of soil by different kinds of instruments can be built, that will
allow fast and qualitatively to investigate processes of processing
of soil and on this basis to perfect existing and to create new
machines for processing of soils which are meeting the demand time.
