To determination of wear-resistance of working bodies of soil machining machines

: In the process of work, wear of the working bodies takes place, the dimensions and their shape change, which leads to disruption of the technological process of soil cultivation, to a decrease in yield, productivity of aggregates, loss of time, labor and materials. Premature wear of the working organs is so great that the use of modern technical means to increase their wear resistance and durability is economically justified. Particularly difficult in this problem is the search for effective solutions that ensure an increase in the resource of working organs, including soil-cutting details. To solve this problem with the use of modern technological tools are checked. Systematically wear resistance of the working bodies of the machine for processing experiments creating optimal technical solutions. Abstract: The computational (numerical) diameter is used to completely solve the problem of approximate differentiation of a function given inexact information in the form of an arbitrary finite set of trigonometric Fourier coefficients.
