Concrete is the name given to the material resulting from the appropriate mixture, known as mix ratio, of cement, water, coarse aggregate (gravel) and fine aggregate (sand). The composition of this material with steel bars generates the reinforced concrete. When in its plastic or fresh state, concrete can be molded in desired shapes and dimensions. On the other hand, when...
This article will present a successful case study performed by Kot concerning the structural analysis of a stacker. Before starting the case study, some basic auxiliary concepts are shown below. Basic concepts about structural analysis Stockyard machines: these are widely used, mainly in mining and port activities for bulk handling;Stackers: stockyard machines used for piling up bulk materials;Tripper: movable belt conveyor,...
Mobile Crushers The mobile sizing rig concept is not new to mining professionals. However, its use has only become more widespread in recent years, due to advances in related areas of engineering. When compared to stationary systems that rely on off-highway truck transport, mobile sizings have significant advantages, the main ones being [1]: Cost savingsReduction of manpower required for the operationDecreased...
Introduction 2021 was marked by several obstacles and challenges that tested the management capacity of companies from all sectors. With the beginning of the vaccination against COVID-19, the expectation was that there would be a quick return to normality, but several setbacks throughout the year compromised the Brazilian's and global economic performances. Although this positive expectation has advanced the confidence indexes...
Engineering is continuously evolving, improving the way analysis and calculations were once made during projects. Today, new applications, systems and computer models are used, ensuring greater efficiency in processes. Simulations have been optimized over time, following modern technologies, including the Multiphysics branch. FSI - Fluid-Structure Interaction, is a recurring term in discussions about this subject. Next, it will be discussed what...
As briefly discussed in the Successful Case: Railway Center Buffer Coupler Analysis article, Industry 4.0 has inherently brought several innovations to the industry in general and one of these innovations was digital simulations. The objective of this article is to show how these computational techniques have changed the course of companies that deal with engineering. The growing demand for cost reduction...
Computer vision is one of the most important areas of artificial intelligence in the tech business. As can be seen in this article, computer vision has transformed the way many companies and industries handle their processes and operations. Therefore, this article discusses the main applications of this concept, through the following topics: What is computer vision?;How computer vision is applied in...
Risk assessments on belt conveyors are extremely important for reliable operation in general. According to international standards, which aim to establish the elements and procedures for risk management, risk can be defined as the result of uncertainty in the expected objectives. Uncertainty, in turn, consists of the absence of concrete data regarding an event, its understanding, the probability of its...
Reading Time: 4 minutes Introduction: Railway vehicles are complex mechanical systems consisting of hundreds of moving components that interact with each other through frictional forces, suspension systems, and unstable operating conditions.
Reading Time: 4 minutes Introduction: In several scenarios in the industrial context, it is possible to observe interactions between a solid object and a flowing fluid.
