摘要

针对大兆瓦风力机滑动轴承齿轮箱疲劳可靠性问题,以6.2 MW浮式风电齿轮箱为研究对象,综合考虑齿轮内外部激励、随机载荷、电磁特性、滑动轴承等,建立随机风速作用下风电齿轮箱机电耦合动力学模型,研究随机风速作用下传动构件的动态特性;采用断裂力学理论,表征传动构件在全生命周期的强度退化过程;基于可靠性设计理论和模糊可靠性理论,建立考虑许用磨损量的模糊性的滑动轴承风电齿轮箱时变可靠性模型,探究强度退化和低速级滑动轴承对风电齿轮箱时变可靠性的影响规律。通过试验对比验证,理论模型精度满足工程需求。

Abstract

Due to the fatigue reliability issues of sliding-bearing gearboxes in large-megawatt wind turbines, the 6.2 MW WTG is taken as the research object. Internal and external excitations of gears, random loads, electromagnetic characteristics, and sliding bearings are comprehensively considered. The electromechanical coupling dynamics model of the WTG is built under random wind speed. The dynamic characteristics of the transmission components are studied. The strength degradation process of the transmission components throughout their life cycle is characterized using fracture mechanics theory. Based on reliability design theory and fuzzy reliability theory, a time-varying reliability model of a sliding-bearing WTG considering the fuzziness of allowable wear is established. The influences of strength degradation and sliding bearings on WTG's time-varying reliability are explored. Through experimental comparison and verification, the accuracy of the theoretical model meets engineering requirements.
