An intelligent detection method for rolling bearings based on PSODACCIW-VPMCD

针对VPMCD中模型选择方法的不合理和小样本多分类时识别率降低的缺陷,结合动态加速常数协同惯性权重的粒子群(Particle swarm optimization with dynamic accelerating constant and coordinating with inertia weight,PSODACCIW)算法的全局优化能力和加权融合理论,提出基于PSODACCIW-VPMCD的滚动轴承智能检测方法。首先对样本提取特征变量,然后采用PSODACCIW算法优化诊断融合权值矩阵,最后对滚动轴承的故障类型和工作状态进行分类和识别。实验结果表明,该方法能够有效地应用于滚动轴承的智能检测中。

Aiming at the unreasonable model selection method and the defect of lower recognition rate for smaller samples and multi-classification,combining the global optimization ability of the particle swarm optimization with dynamic accelerating constant and coordinating with inertia weight（ PSODACCIW） algorithm and the weighted fusion theory,an intelligent detection method for rolling bearings based on PSODACCIW-VPMCD was put forward. Firstly, the characteristic variables of samples were extracted,then the PSODACCIW algorithm was used to optimize the diagnosis fusion weighting matrix. Finally,the operation status and fault pattern of rolling bearings were classified and identified.The test results showed that the proposed method can be applied in o rolling bearing intelligent detection effectively.
