Optimization of the power design of soil tillage equipment using the "LARI" pluge harrow

Abstract

In this article, the method of calculating the frames of agricultural trailers using topological
optimization algorithms is considered. The work was carried out in order to increase the
competitiveness of the products of Ukrainian manufacturers by reducing the weight and cost of power
frames while maintaining their strength characteristics in all modes of operation of the trailer.
To carry out the optimization, one of the basic models of the cultivator produced by the
company "Lozivski Mashyny" was taken, and a number of optimization calculations were carried
out to obtain first the topology, and in the rest, the design of the power frame for this type of units.
As a result of the research, the optimal topology of the key nodes of the unit frame was
established and a number of technological design elements were developed. The obtained data are
presented in the article graphically, and a verification analysis of the strength of the requirements
for this type of structures was carried out. The analysis of the obtained structure proved the correctness of the chosen optimization
methods, and showed that the obtained characteristics of the power frame meet the requirements for
the operation of agricultural machinery
