In this paper, a full analysis of voltage vectors (VVs) in the DTC algorithm is presented. The analytical analysis shows that the application of specific VVs results in false switching states called uncontrollable angles (UCAs). A robust scheme that...

Due to the unique geometry of the models of anatomical structures, manufacturing them using subtractive methods is difficult or often impossible. This situation makes the additive processes an ideal alternative for manufacturing this model type. Many...

The general design of the wheeled vibration-driven robot is developed in the SolidWorks software (Dassault Systèmes SolidWorks Corporation, Premium 2022, Waltham, MA, USA) on the basis of a double-mass semidefinite oscillatory system. The idea...

The distinction of inter-turn short-circuit faults (ITSCF) from abnormal conditions, such as an unbalanced voltage supply condition, has been challenging over the last few years. The asymmetries caused by both conditions are similar, therefore the de...

Production systems are becoming increasingly complex, which means that the main task of industrial maintenance, ensuring the technical availability of a production system, is also becoming increasingly difficult. The previous focus of maintenance eff...

In motion simulation, motion platforms enable the simulation of forces and angular velocities acting, for example, on a person in a car or in an airplane. Other applications include perceptual research and testing the dynamic behavior of mechanical s...

Fault diagnosis in electrical drives can be very difficult, especially when the input data come from an operating electrical machine. The occurrence of inter-turn short-circuit (ITSC) faults is one of the most dangerous electrical machine failures, a...

Maintenance strategies are one of the key aspects determining the availability of a production system and its maintenance cost. For complex machines with multiple components, each of which can have several failure modes, maintenance strategy selectio...

The objective of this paper is to present the development of a novel nonmotorized mechanism for ankle rehabilitation. The mechanism is based on the four-bar linkage. The mechanism transmits angular movement generated by the patient’s hand to an...

With a constant increase in heat pump (HP) use, it has become of great importance to use the application of fault diagnosis (FD) methods to detect faults at an early stage and thus ensure a proper working condition and improve the reliability of the...

This work is devoted to the analysis of the application of object detection algorithms for recognizing the level of blood in a test tube. Based on the initial data and data received from the sensory system, pattern recognition is performed and decisi...

Prefabricated utility tunnels play an important role in modern urban infrastructure construction. However, prefabricated utility tunnel segments are heavy, and the hoisting conditions are complicated, resulting in increased requirements in terms of t...

Synchronous generators (SGs) play a vital role in energy production as well as in the industry. Their insulation system, where epoxy resin and mica dominate among the most common insulation materials, plays the most significant role in proper operati...

Induction motors operate in difficult environments in the industry. Monitoring the performance of motors in such circumstances is significant, which can provide a reliable operation system. This paper intends to develop a new model for fault diagnosi...

This work was devoted to the optimization of the trajectory of a robotic system for aliquoting biosamples, consisting of serial and parallel manipulators. The optimization consisted of two stages. At the first stage, we considered the optimization co...

One of the important problems in verifying the dimensional and geometrical accuracy of products is measuring in difficult-to-reach places. One of the non-destructive measurement methods is the indirect measurement, using the replication technique. Th...

Poly ethylene terephthalate glycol (PETG)-filament gives excellent layer adhesion, thus it is widely used in fused deposition modeling (FDM). To achieve process repeatability, process parameters and product geometrical accuracy should be correlated....

Aiming at the problems of the moving stability of the mobile station of the hydraulic press, the reliability of the mobile station clamping during the workpiece forging process, and the force requirements of the mobile station, an innovative design o...

The improved design of a vibratory lapping machine is developed in the SolidWorks software on the basis of a suspended double-mass oscillatory system. The system is set into motion by three pairs of electromagnets generating periodic excitation force...

An autonomous excavator can be a good solution in the construction industry to deal with existing issues such as high labor costs and harsh and hazardous environmental conditions. To increase energy efficiency for autonomous excavators, this study pr...

Ultrasonic sensors are commonly used as affordable methods to measure distance in industry. However, the accuracy of their measurements is often low, especially when inexpensive sensors and reasonably low-priced equipment are used. In this article, a...

The assembly process is one of the most important spots in the process of product production. A reasonable assembly sequence can not only reduce the assembly workload but also reduce the manufacturing cost of products. Therefore, this paper proposes...

Elastic emission machining (EEM) is a finishing process for the surface of parts. In the EEM of ceramic parts, the part is submerged into a liquid interface that contains abrasive particles, and then a spindle rotates a spheric tool rapidly, forcing...

In the construction industry, excavation is a difficult task that needs to be automated to save on resources such as cost, time, and labor. In this paper, a prototype of an excavating drone is presented which can operate totally autonomously without...

During Abrasive Waterjet (AWJ) machining of hard-to-cut materials, apart from other important process parameters, the properties of the abrasive material can considerably influence the outcome. In this research, the efficiency of silicon carbide as a...

In this paper, a combination of marching cubes and the constructive solid geometry method were merged to develop a simple, fast, and accurate method to estimate the shape of the soil in addition to the volume of the soil in the bucket during the digg...

The high load capacity and the harsh working environment of mining dump trucks require suspension structures with good damping properties and simple structures. Hydro-pneumatic suspensions are widely used due to their non-linear stiffness and damping...
