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.
