Tehergépjárművek menetadatainak elemzése egy meghatározott szállítási útvonalon
Megjelent április 15, 2020
347-352

Ebben a tanulmányban egy állandó útvonalon közlekedő tehergépjármű mozgását leíró menetciklus létrehozását tárgyaljuk. Kiválasztottunk egy jellemző szállítási útvonalat, ahol olyan tehergépjárművek közlekednek, melyek fel vannak szerelve megfelelő adatgyűjtő berendezéssel. Hosszú távon gyűjtöt...tük a jármű mozgását leíró adatokat, majd az adatokat egy saját fejlesztésű célszoftver segítségével szűrtük és készítettük elő, végül a tisztított adatokat statisztikai eljárások alkalmazásával dolgoztuk fel.

Review on Construction Procedures of Driving Cycles
Megjelent április 15, 2020
266-285

The goal of this paper is to give an overview of the literature of construction techniques of driving cycles. Our motivation for the overview is the future goal of constructing our own driving cycles for various types of vehicles and routes. This activity is part of a larger project focusing on determination of fuel and energy consumption by dy...namic simulation of vehicles. Accordingly, the papers dealing with sample route determination, data collection and processing, driving cycle construction procedures, statistical evaluation of data are in our focus.

Defect analysis of bearings with vibration monitoring and optical methods
Megjelent február 13, 2018
1-12

Diagnosis of bearings with advanced methods gained remarkable roles in the previous years. This article focuses on the manufacturing defects and methods to reveal and classify them. During manufacturing several faults could emerge because of the grinding operation, tool wear and chatter vibration. Inproper handling of the bearing parts because ...of the collosion to each other and the storing box that causes deformation. To reveal these problems several methods are applied in industry. For deeper surface analysis nitric acid can be used to initate the finished surface of the roller then natrium-carbonate that nautralize the elements. Vibration analysis in its standard Fourier form is not a new achivement but other mathematical tools could be applied to condition monitoring such as wavelet transform. It is an efficient tool for analyzing the vibration signal of the bearings because it can detect the sudden changes and transient impulses in the signal caused by faults on the bearing elements. In this article five different wavelets, Daubechies, Gaussian, Coiflet, Mexican hat, Meyer are compared according to the Energy to Shannon Entropy ratio criteria to reveal their efficiency for fault detection.
