This article deals with the creation of control algorithm for locking differential of the truck. This algorithm is based on assumptions of the ZF ADM — Automatic Drive-Train Management system and it is created using software Simulink-Stateflow. The article describes the function of algorithm and its application to the computational model of vehicle with 8×8 drive. In conclusion, a simulation of driving...
Safety of transport means is a priority for manufacturers and it is a subject of strict standards. The present article describes a method for measurement of displacement in compression tests of forks arm of the motorcycle made from aluminum alloy AlSi7Mn0.3. The test is performed on the universal hydraulic press. The standard output of this test is a stress stain diagram that will give us information...
The problems of using of mechatronic devices as a part of a ship unified high voltage electric power system (EPS) is considered. EPS contains a turbo generator source of high frequency electric power (200 Hz), an electric propulsion system (PS) and a system of power takeoff (SPT). The system of power takeoff is used for the supply of common ship consumers with the common mains frequency (50 Hz). Specified...
The paper is focused on communication signal transmission over specific topology of medium-voltage overhead power distribution lines with crosstalk between different power sections. The following parameters have been measured and modeled: channel frequency response, interference, background noise. On this basis we have set up models and computed the estimated data throughputs for narrowband Power...
The paper deals with transmission of communication signals over low-voltage power distribution lines. Narrowband data transmission for Smart Metering systems is considered. The probability of data frame loss is derived, based on practical experiments, and its impact on the efficiency of reading data records from electricity meters is discussed. Furthermore, communication system with frequency-shift...
With an increasing number of small devices, the concept of LPWANs becomes more popular. The most important requirements on LPWANs include long battery lifetime, low price of devices, ability to connect millions of devices and long range coverage; the long range coverage is the most critical issue of this technology. In this paper we discuss indoor signal propagation of LoRa technology. At the beginning...
Energy harvesting systems are alternative electric power sources for supplying low-power electronics from their ambient. In the case of electromechanical energy conversion, the ambient energy to be considered is mechanical vibrations. This paper deals with establishment of methodology for initial estimation of reliability and dependability characteristics of electromagnetic vibration energy harvesting...
Due the previous work of the authors, the technical textile materials were successfully used as a protection against the undesirable external magnetic field. The woven textiles (compound of cotton, polyester, and conductive fibers) were analyzed before in 2D finite element environment. The mechanical (and electrical) structure of the material has been simplified as a 2D thin layer, and the simplification...
Spherical induction motors hold great potential for numerous applications where design of multi-degree of freedom drive systems is needed, such as mechatronic systems, robotics, automotive industry and medical applications. Namely, spherical induction motor can operate in several degrees of freedom due to its specific design features. In addition, the drives where spherical motors are used might be...
The paper deals with detection, localization and handling of single-phase-to-ground faults on medium-voltage power distribution lines. Fault location principle of zero-sequence current phase is described. Results of MATLAB simulations are provided. Design of a system for localization of a single-phase grounding fault section in distribution network is proposed. Arrangement of power line communication...
The paper is aimed at the design, implementation and experimental functional verification of the machmeter manufactured using common available components and pressure sensors. As a basis of the machmeter a universal platform Arduino UNO R3 was utilized. Projected Mach number measurement range is from 0.4 to 1.2. That means for subsonic and transonic speed of flight measurement. The paper includes...
