Abstract

Ovaj rad proučava hidrauličko vitlo šumskog traktora s fokusom na poboljšanja u radnoj učinkovitosti kroz uvođenje hidropneumatskog, odnosno hidrauličkog akumulatora. Nakon uvodnog opisa vitla, specifičnosti hidrauličkog vitla, opisa hidraulike, u radu se analiziraju ključni aspekti rada vitla kao što je trenje ovisno o brzini. Predložena modifikacija hidrauličkog sustava uključuje integraciju hidrauličkog akumulatora kao sredstva za pohranu energije. Objašnjen je princip rada akumulatora, ističući njegovu ulogu u povećanju energetske učinkovitosti vitla. Potreban volumen hidrauličkog akumulatora određen je pomoću računalnog modela a rezultati simulacija pružaju uvid u rad vitla i daju učinke uvođenja hidrauličkog akumulatora u sustav. Rad kombinira teorijski pristup i simulacije pomoću programskog paketa MATLAB.

Abstract (english)

This paper studies the hydraulic winch of a forest tractor with a focus on improvements in working efficiency through the introduction of a hydropneumatic or hydraulic accumulator. After the introductory description of the winch, the specifics of the hydraulic winch, the description of hydraulics, the paper analyzes the key aspects of winch operation such as speed-dependent friction. The proposed modification of the hydraulic system includes the integration of a hydraulic accumulator as a means of energy storage. The principle of operation of the accumulator is explained, highlighting its role in increasing the energy efficiency of the winch. The required volume of the hydraulic accumulator was determined using a computer model, and the results of the simulations provide insight into the operation of the winch and give the effects of introducing the hydraulic accumulator into the system. The work combines a theoretical approach and simulations using the MATLAB software package.
