Dynamic assessment and diagnosis of vibration of rolling bearings using grey bootstrap

  • 摘要: 以灰预报和自助再抽样方法为基础, 提出灰自助动态评估与诊断模型, 以评估和改进滚动轴承的振动.该模型用动态不确定度、估计区间、估计真值、平均不确定度、平均真值和系统误差测度等6个参数, 描述滚动轴承振动的基本特征.对HKRB轴承的试验表明, 该模型对随机误差的概率分布与系统误差的类型没有任何要求, 在平均不确定度为最小的条件下分离出系统误差.评估的可信度达到100%.根据灰自助动态评估结果, 还诊断出影响轴承振动的误差特征, 揭示了来自轴承零件制造的误差根源, 为实施滚动轴承振动的生产过程控制奠定了基础.
