Abstract

The article describes a strain gauge measuring system designed for measuring the traction resistance of tillage bodies and their combinations. Technical tools measure the traction resistance of the whole machine or one working body which is not an objective and reliable characteristics of combined tillage units. The design and principle of operation of the tensometric measuring system designed and manufactured by Samara State Agrarian University is described. It is used to determine the traction resistance of individual working bodies and their combinations. The results show that the measurement data on traction resistance are in compliance with the calculated values.

Highlights

A steady trend in the development of modern machine designs and tillage technologies is a combination of several different technological processes of tillage [1, 2]
Important features of the soil treatment using combined machines is the mutual influence of combination elements, for example, the imposition of soil deformation zones, the need to coordinate the paths of movement of soil particles, etc
To relieve the force of traction resistance of the working bodies between the movable and non-movable parts of the frame, strain gauge S-shaped compression-tension sensor 11 is designed for a force of up to 50 kN

Summary

Introduction

A steady trend in the development of modern machine designs and tillage technologies is a combination of several different technological processes of tillage (loosening, crumbling, mixing or changing the vertical position of its layers, surface alignment, soil compaction, etc.) [1, 2]. Technical tools measure the traction resistance of the whole machine or one working body which is not an objective and reliable characteristics of combined tillage units. The system consists of a strain gauge unit (Figure 1, 1) aggregated with tractors of traction class 5, and an information-measuring system (Figure 3, 4).
