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

The export of grains plays a pivotal role in the global economy, and the implementation of efficient container loading systems is of paramount importance for reducing time and resource expenditure. This study aims to develop a stationary hoist designed for loading grain into containers for railway transportation. The application of direct integration and matrix force methods enabled the calculation of static and dynamic stresses in the load-handling frame. Simulations of the container filling process were conducted to evaluate the dependency of time and speed on the results. The results demonstrated that the maximum normal stresses satisfied the strength conditions, while dynamic stresses were calculated based on the falling height of the grain. The findings revealed a relationship between the hole radius in downcomer pipes and the container filling time, providing valuable insights for optimizing hoist operation. The research offers practical relevance for grain producers, transportation companies, and researchers, contributing to more efficient grain loading and transportation.
