2MW风电机组变桨减速器可靠性分析
Reliability Analysis of a 2 MW Gearbox for Wind Turbine Pitch Control
摘要
Abstract
Based on the theory of interference for stress-strength distribution, this paper established reliability models of important parts which consists of all important parts such as gears, planetary axes, bearings and splines in planetary transmission. Whole system reliability was formulated on the combination with system reliability theory and characteristic of hybrid system of multi-stage planetary transmission. And corresponding analysis software compiled with VC ++ was developed, with which self-developed and foreign pitch gearbox for wind turbine and foreigners were analyzed to have the same reliability. Through the reliability analysis results, system reliability can be upgrading by improving weak parts, which supports the reliability optimization.关键词
