摘　　要：针对小样本和概率分布未知的乏信息问题,建立滚动轴承质量数据序列真值融合模型,对滚动平均法、隶属函数法、最大隶属度法、滚动自助法和算术平均法的估计真值进行融合,进而获得最终估计真值。通过对圆锥滚子轴承的质量参数进行蒙特卡洛模拟和试验研究,以验证文中所述融合方法的适应性和有效性。Aiming at the poor information problem about small sample and unknown probability distribution,a true value fusion model is proposed for quality data sequence of rolling bearings.The estimation true values of rolling mean meth-od,membership function method,maximum membership grade method,rolling bootstrap method and arithmetic mean method are fused,and the final estimation true value is obtained.The Monte Carlo simulation and experimental investi-gation are carried out for quality parameter of tapered roller bearings to verify adaptability and effectiveness of fusion method.
