Substantiation effectiveness of local strengthening cultivator paws using wear-resistant material

Abstract

Purpose. Reducing the cost of technological operations for tillage due to increased resource cultivator paws. Methods. Monographic, mathematical-statistical, economic-mathematical, graphic-analytical. Results. The methodical approach to determining the economic efficiency of local hardening of cultivator paws using wear-resistant powder material with the aim of increasing the resource is substantiated. The limits of increasing the resource of cultivator paws KPE-410 and the maximum value of the cost of its hardening for the effective functioning of industrial enterprises are substantiated. Conclusions. The effectiveness of local hardening of the cultivator paw KPE-410 using wear-resistant powder material is achieved under the condition that the resource of the hardened cultivator paw is more than 18.7% of the serial sample. Provided that the resource of the strengthened cultivar's paw is 37% of the serial, in order to ensure efficiency, the cost price of hardening of one cultivar's foot KPE-410 should not exceed 112.5 UAH. It was established that with the cost of hardening of the cultivar leg Sz = 53.77 UAH and its resource 55 hectares, the economic efficiency is 109%.
