DEFINITION OF RATIONAL TRACK PARAMETERS EXCAVATOR CRAWLER ENGINE

Abstract

The article has developed a mathematical model for determining the rational parameters of a tracked vehicle track by the criterion of minimum metal consumption. For the correct conduct of the computational experiment, the basic assumptions used in the mathematical model are accepted. The schemes of the external load on the track track are proposed and the design schemes of the track as a beam with a distributed load on the ground side and a concentrated load on the side of the track rollers of the caterpillar drive are developed. The internal force factors arising in cross sections that are taken into account when determining the metal consumption of a truck are determined. Comparable typical track track designs have been developed. The paper presents an enlarged algorithm of the mathematical model and determines the investigated geometric parameters of the track track. Constant initial data and variable geometric parameters of the truck, which affect the metal consumption of the truck, are separately highlighted. Based on the results of the computational experiment, we obtained graphs of changes in the metal consumption of the truck depending on the length of the truck, the height of the sole of the truck and the design of the truck. It is shown that there are rational parameters and a rational design of the track track. The decrease in the metal consumption of the truck when choosing rational parameters and the rational design of the truck can reach 92%.
