Mjerenje razine buke internih prometnica proizvodne metalurške tvrtke

This publication shows the results of measurements of the noise level emitted by the motor trucks on the internal roads of the steelworks. The distribution of the metallurgical products with the use of trucks is, next to the rail transport, one of the main logistic forms of products delivery to the customer. The research was conducted on one of the busiest internal roads of metallurgical enterprise ArcelorMittal Poland in Dąbrowa Górnicza. The enterprise conducts the whole production cycle and is the biggest steel producer in Poland. On the premises of the steelworks there were five points of measurements marked where the noise level is measured and the results were compared with the acceptable noise levels defined in the norms.Članak daje rezultate mjerenja razine buke emitirane od motornih vozila internih prometnica čeličane. Distribucija metalurških proizvoda rabeći ova vozila uz željeznički transport je najvažniji način isporuke proizvoda kupcima. Istraživanja su provedena na najprometnijoj internoj prometnici metalurške tvrtke ArcelorMittal Poland u Dąbrowa Górnicza. Poduzeće sadrži sve proizvodne cikluse i najveći je proizvođač čelika u Poljskoj. Unutar prostorija čeličana odabrano je pet točaka gdje je mjerenja razina buke, a rezultati su uspoređivani sa prihvatljivim razinama buke zacrtanim u normama

Identifikacija i iskorištavanje cestovne prašine

The aim of this publication is to determine models of explore dust from vehicle brake systems and the presentationof measurement results of the exploitation dust, which is separate from road dust. The following methods and measuring devices were used: T-01M device, screen analysis, analysis of chemical composition with the use of a scanning microscope with Energy Dispersive x-ray Spectroscopy (EDS) analyser. The measurements for identifying this type of dust were conducted on marked sections of roads: motorway, city road and mountain road. The explored dust was distinguished in the following car systems: brakes, clutch plates, tyres and catalytic converters.Cilj ove publikacije je utvrditi modele upotrebe prašine, koja je odvojena od cestovne prašine. Za ispitivanje su korištene sljedeće metode i mjerni uređaji: T-01M uređaj, granulometrijska analiza i upotreba pretražnog elektronskog mikroskopa s energetsko disperzijskim spektrometrom. Za mjerenja su uzeti uzroci prašine na različititim dijelovima ceste: autoceste, gradske i planinske ceste. Istraživana prašina potječe od sljedećih dijelova automobila, kočnice, spojke, gume i katalizatora
