Considering the structural characteristics and multi-source excitations of sliding-bearing wind turbine gearboxes, this study constructs a multi-body dynamic model of high-power sliding-bearing wind turbine gearboxes. A comprehensive performance evaluation methodology is proposed, integrating the analytic network process (ANP) with an improved fuzzy comprehensive evaluation (IFCE). A multidimensional comprehensive performance evaluation framework, emphasizing the practicality and cost-effectiveness is developed consisting of target, criterion, and indicator layers. The key evaluation indicators identified within this framework include the main shaft bearing support force, transmission system reliability, load-sharing coefficient, vibration characteristics, and power density. Utilizing ANP and IFCE methodologies the comprehensive performance of two sliding-bearing wind turbine gearboxes is systematically assessed.

• Title: Celovita ocena zmogljivosti zobniških prenosov vetrnih turbin z drsnimi ležaji

Abstract

Ob upoštevanju strukturnih značilnosti in večizvornih vzbujanj zobniških prenosov vetrnih turbin z drsnimi ležaji ta študija oblikuje večtelesni dinamični model visokozmogljivih zobniških prenosov z drsnimi ležaji. Predlagana je celovita metodologija za ocenjevanje zmogljivosti, ki združuje analitični mrežni proces (ANP) z izboljšano metodo mehke celovite ocene (IFCE). Razvit je bil večrazsežen okvir za celovito ocenjevanje zmogljivosti, ki poudarja praktičnost in stroškovno učinkovitost, ter vključuje ciljno, kriterijsko in indikatorsko raven. Ključni kazalniki ocenjevanja v tem okviru vključujejo podporno silo ležaja glavne gredi, zanesljivost prenosnega sistema, koeficient delitve obremenitve, vibracijske značilnosti in gostoto moči. Z uporabo metodologij ANP in IFCE je bila sistematično ocenjena celovita zmogljivost dveh zobniških prenosov vetrnih turbin z drsnimi ležaji.
