Sound visualization tools are now widely used in industry. As a tool, acoustic cameras are also well- suited for faster identification of errors as well as individual states while operating devices. The aim of this paper was to locate and quantify noise sources on a packet sorting line using an acoustic camera and then to propose noise reduction measures. Localization of noise sources was performed...
The non-destructive tests (NDT) of the steel wire ropes put on the crane pulley blocks comprise more than a half of our NDT services. The intensive utilization of cranes often leads to critical situations endangering health and safety at work. The operators are forced to provide safety use of the cranes due to new cranes constructions, new construction of the block pulley and put on the new steel...
Implementation of modern handling facilities contributes to the quality performance of each business subject. Nowadays, mechanization and automation of processes associated with the handling of shipments finds an important place especially under the conditions of the postal and logistics sector, which is growing due to ecommerce. The method of allocating large mechanization and automation, the performance...
The subject of the research was a undercarriage leg of a gyroplane made of composite materials. The aim of the work was to assess the level of damage initiation of the composite gyroplane undercarriage. In the study, a structural capacity analysis was carried out, taking into account the phenomenon of damage initiation. Numerical calculations were conducted based on the finite element method in the...
The wastes which infiltrate into the environment are created from unexpended materials and products. The environment can manage a great amount of waste, but this process requires time. Nature always attempts to achieve the balance . However, degradation of some materials in nature takes about 1000 years, which is a very long period of time in terms of the length of a human life, also in view of the...
The aim of the work is to change the current program in the programmable logic controller (PLC) to be as close as possible to the real-world Pick to Light system in the automotive industry for installing individual car components. The change consists in completing the navigation and tutorial mode while preserving the original function of the program, which is to measure the time of each step in assembly...
The first step in the process of detection a license plate is to determine the location of the plate. The output of this stage should be accurate enough and calculations will be completed within a short time. The reason for this is that the output of this stage is as input in the next steps. If the step to determine the location is encountered error, then the operation of the next steps will also...
A process of quality development helps us reveal concrete deficiences, an analysis of their origin and realization of required modifications that are needed to solve a concrete problem. One of the aims of quality development of production in bearing industries is to find out an impact of tchnological conditions to form burning of surfaces in grinding of orbits of bearing rings. We try to describe...
The paper focuses on the optimization of production logistics within the selected company, which is going to relocate the machining centre to the Czech Republic. The aim of this paper was to design a suitable conveyor to optimize the machining centre’s entire production process. On the basis of the company’s input requirements, the necessary calculations were carried out, which led to the construction...
Limited possibilities of agricultural utilization of sewage sludge results in the development of unconventional methods of its final management. Recently, recycling of sewage sludge in road construction is under examination. Literature review mentions that properly prepared sludge might replace other conventional materials which are commonly used in a construction sector. In this paper, the proposition...
This article deals with a three hybrid modeling methods of virtual skull implants, developed by the author. 3D models of cranial implants are nowadays necessary for the creation of real implants using modern manufacturing technologies. These methods combine simultaneous usage of three modeling systems (which causes their hybridity): computer tomography system (as a reverse engineering system), surface...
During the processing of the thin packaging sheets by drawing, thickness of the material changes and so does the thickness of tin layer, this has an influence on corrosion resistance. Change in material thickness of the cylindrical cups without a flange has been evaluated in this contribution. Cups were produced from the double reduced continuously annealed packaging sheets. After cupping test, the...
The object of this study involves thin-walled columns made of carbon-epoxy composite with open top-hat cross-section. The material used comprised a composite of epoxy matrix reinforced with carbon fiber (system HexPly M12, Hexcel). The M12 system is used above all in aircraft structures. It exhibits high fatigue durability and good maintenance properties at relatively low specific gravity. The research...
The Internet of Things (IoT) paradigm is referring to the underlying constituents of the 4th Industrial Revolution that will also affect the use of the internet in industrial production in the future. More than 50 billion smart devices will be able to communicate with each other and internet services over the increasing network capabilities of wireless sensor networks nodes on IoT applications in...
Sound visualization methods and techniques are currently applied in various fields to identify and locate individual sources of noise. Conveyor systems are used in various industrial plants. Conveyors require regular inspection and maintenance. In some operations, conveyor systems are difficult to access for the maintenance purposes. During their operation, conveyor systems contribute to increasing...
Designing of the conveyors and its control system with control program through the design tool “Virtual Commissioning” is very important in the digital era Industry 4.0. Virtual Commissioning was recently used to perform realistic virtual simulations in the early stages of development processes in automation of the conveyors too. The main benefit is the possibility of integrating and testing the control...
A mathematical model of dynamic processes in pumping unit of a drilling rig with friction clutch, taking into account variable moment of inertia of slider-crank mechanism links and random number of pistons of the pump, was developed. Joint integration of differential equations of motion of pumping unit parts was carried out with numerical methods. The calculations performed considered the torque moment...
Numerical analysis of the carrying frame subassemblies strength installed in the friction lift was presented in this article. Two models of the frame loading were introduced. One of them was applied during loading and the other one during regular operation with nominal load capacity. Finite Element Method was used for calculations. It allows mapping the actual operating conditions by using commercial...
Apart from the object, a controller constitutes of the fundamental elements of control systems. However, such controllers, even in SISO (Single Input, Single Output) systems where a single output is controlled by a single input, may not be the most appropriate choice. Moreover, a PID controller may not be easily tuned to any setup. The paper outlines three elementary methods for tuning the controller...
The paper deals with the issue of the machining process optimization by using the algorithms that were proposed for the creation of NC strategies in CAD / CAM systems. The possibilities to create NC strategy in CAD / CAM systems using Feature Based Machining were analyzed using Edgecam’s Strategy Manager Module, Mastercam’s FBM Drill, and Machining Knowledge Editor in the Siemens NX10. Strategy Manager...
