Analiza možnosti zamenjave odvalnega valja zračne vzmeti in vpliv na karakteristiko

Janhar, Urban (author), Oman, Simon (mentor), Nagode, Marko (author)

V današnjem času je optimizacija logistike in prevozov eden izmed ključnih dejavnikov za delovanje družbe. Zmanjševanje mase transportnih vozil z namenom povečanja količine tovora, ki ga lahko prevažajo, zmanjšanja porabe goriva in posledično ogljičnega odtisa je trend, ki mu sledijo vsi proizvajalci tovornih vozil. Predstavljena je izbira ter kompleksnost izdelave različnih polimerno kompozitnih odvalnih valjev, ki bi lahko zamenjali obstoječ kovinski odvalni valj. Predstavljen je vpliv na ceno in težo izdelka ter vpliv geometrije in volumna odvalnega valja na statično in dinamično karakteristiko zračne vzmeti. Nova zračna vzmet s polimernim odvalnim valjem iz enega dela ima nekoliko bolj togo karakteristiko kot obstoječa zračna vzmet. Vzmet z novim odvalnim valjem ima v primerjavi z obstoječo zračno vzmetjo maso zmanjšano za 15,4 %.

• Title: Analysis of the possibility to replace the air spring piston and the effect on the characteristics

Abstract

Nowadays, the optimization of logistics and transport is one of the key factors for the operation of the society. Reducing the weight of transport vehicles in order to increase the amount of cargo they can carry, reduce fuel consumption and consequently the carbon footprint is a trend followed by all truck manufacturers. We have presented the selection and complexity of manufacturing various polymer composite pistons for air spring, that could replace the existing metal piston. We presented the influence on the price and weight of the product, as well as the influence of the geometry and volume of the air spring piston on the static and dynamic characteristics of the air spring. The new air spring with a one-piece polymer composite piston has slightly better characteristics than the existing air spring. The spring with the new piston has a weight reduced by 15.4% compared to the existing air spring.
