Paired Modeling of the Tribological Process of the Abrasive Wear of Soil-Cutting Parts
The work of tillage machinery is accompanied by a natural process of abrasive wear of soil-cutting parts, which leads to a decrease in the quality of technological operations and requires consideration in the development of new designs of such parts. The application of the method of paired modeling of the tribological process of abrasive wear makes it possible to obtain the necessary data for choosing the forms of hardening of the friction surfaces of soil-cutting parts, providing them with the required working life. The pair model proposed here is based on a combination of the results of simulation modeling on bench equipment and the values of the measured pressures in real soils in the zones of subsequent operation. Simulation modeling was carried out on a soil background corresponding to medium loamy soils, and during loading, the values of normal pressures were measured at different points of the friction surfaces and geometric shapes of normal pressure plots were built on the entire friction surface of the part. The measurement of the pressures of real soils was carried out by dynamometry of soil-cutting parts on soils intended for operation with the determination of power equivalents of total loading cutting parts on soils intended for operation with determination of power equivalents of total loading. In the paired model, a combination of simulation data and force equivalents of loading obtained under dynamometry conditions is performed, which allows us to have reliable values for the exact selection of materials and geometric shapes of soil-cutting parts focused on the guaranteed service life.
期刊介绍:
Journal of Friction and Wear is intended to bring together researchers and practitioners working in tribology. It provides novel information on science, practice, and technology of lubrication, wear prevention, and friction control. Papers cover tribological problems of physics, chemistry, materials science, and mechanical engineering, discussing issues from a fundamental or technological point of view.
