Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This article is devoted to the development of an automated system for the theoretical study of vibro-impact unloading of bulk cargo on vehicles – dumper trucks. The high efficiency of the technological process of unloading bulk cargo by means of the application of vibro-impact loads is determined.A high degree of intensification of the process of unloading of bulk cargo is achieved by using original vibrating and vibro-impact unloaders with a hydroimpulse drive. The system approach to the unloading technological process (unloading device, process, body, bulk cargo) is considered and an automated system of mathematical modeling of the stress-strain state of the body of a dump truck with vibro-impact unloading is developed.The finite element method in the FEM-program was used to determine the main parameters of the stress-strain state of the body of a dump truck under vibro-impact unloading. The results of automated modeling allowed us to evaluate the effectiveness of the impact of shock loads on the body of a dump truck when unloading bulk cargo, as well as the efficiency of the developed designs of vibration-resistant unloading devices with a hydroimpulse drive.
