中文摘要：
通过对某风电转盘轴承进行加速疲劳寿命试验,分析润滑脂温度、摩擦力矩以及振动加速度信号与故障的关联程度,确定了能够表征风电转盘轴承滚道故障的特征参数,利用轴承的温升、摩擦力矩和加速度的联合趋势判断故障出现的时间,为进一步分析风电转盘轴承故障提供数据支持.
英文摘要：
The accelerated fatigue life test of a slewing bearing in wind turbine is carried out,the relevancy grade of fault with lubricating grease temperature,frictional and vibration acceleration signal is analyzed,and the parameters are determined to characterize raceway fault of slewing bearings in wind turbines.The occurring time of fault is judged by using the trend of temperature rise,frictional torque and acceleration,which provide the data support for further analysis of the fault of slewing bearings in wind turbines.
