Abstract
Cílem práce bylo navrhnout systém využívající lankové elektrody s několika zvlákňovacími jednotkami pro účely laboratorního testování a výzkumu. Byla provedena rešerše různých typů technik elektrospinningu a používaných zvlákňovacích elektrod. Byla navržena varianta s použitím dvou kladek a ocelového lanka, které je poháněno pomocí servomotoru. 3D model konstrukčního návrhu byl vytvořen v softwaru PTC Creo 4.0 a byly vypracovány výrobní výkresy. Byla provedena analýza elektrického pole v okolí lanka a v okolí kladky, aby se ověřila bezpečnost návrhu kladky. Byla rovněž zkoumána závislost intenzity elektrického pole na vzdálenosti mezi dvěma elektrodami. Pro analýzu elektrického pole byl použit software Autodesk Simulation Mechanical. Pro výběr nejvhodnějšího servopohonu pro tento systém byla provedena dynamická analýza systému lankových elektrod.
The thesis aims to design an AC cable electrode system with multiple spinning units for the purpose of laboratory testing and research purposes. Research was done on the different type of electrospinning techniques and electrodes were studied. A variant was suggested with the use of two pulleys and steel cable which operated with the use of a servo motor. The 3D modelling of the proposal was made in the software PTC Creo 4.0 and the manufacturing drawings were drafted. Electrical field analysis of the cable and pulley edge radius was done to verify the safety in the design of the pulley. The distance between two electrodes were also studied from the results of the electric field interference analysis done between two electrodes. The software used for the electric field analysis was Autodesk Simulation Mechanical. Dynamic analysis of the cables electrode system was carried out for the selection of the most appropriate servo drive for this system.
