Offer Description
Vplyv kmitania náradia a preklzu kolies na výkonnosť agrotechnickej súpravy
Influence of implements vibration and tyres slip on the agricultural machinery performance
Supervisor: doc. Ing. Jozef Rédl, PhD.
Workplace: Faculty of Engineering
Field of study: Engineering
Study program: Technique and mechanization of agricultural production
Form of Study: daily/external
Hlavné myšlienky (tézy) navrhovanej témy: Práca je zameraná na zhodnotenie energetických strát agrotechnickej súpravy pri výkone vybranej agrotechnickej operácie. Cieľom je vytvorenie rôznych variantov matematického modelu pohybu agregátu s náradím pri výkone agrotechnickej operácie so zohľadnením strát, ktoré vznikajú vplyvom nežiadúceho kmitania a preklzu kolies. Metodicky je nutné zvoliť vhodný matematický aparát ako aj návrh vhodného modelového softvéru a meracieho reťazca. K dispozícii sú komerčné produkty Matlab, Mathcad. Na základe zostavených modelov bude nutné zvoliť vhodné parametre, ktoré rešpektujú reálne prevádzkové podmienky. Zostavené modely budú potom budené získanými reálnymi prevádzkovými budiacimi funkciami. Následne sa budú realizovať simulácie pre rôzne prevádzkové podmienky a vyhodnotia sa výsledky simulácií. Na základe získaných výsledkov sa vypracujú odporúčania pre prax. |
Main ideas of the proposed dissertation topic: The work is focused on evaluating the energy losses of agrotechnical equipment during the performance of a selected agrotechnical operation. The goal is to create different variants of the mathematical model of the movement of the machine with implements during the performance of an agrotechnical operation, considering the losses that arise due to unwanted vibrations and wheel slippage. Methodically, it is necessary to choose a suitable mathematical apparatus and suitable model software and measurement devices. Commercial products Matlab and Mathcad are available. Based on the designed models, choosing appropriate parameters that respect real operating conditions will be necessary. The obtained real technical functions will then actuate the designed models. Subsequently, simulations will be carried out for different operating conditions and the results of the simulations will be evaluated. Based on the obtained results, practice recommendations will be drawn up. |
