基于量子启发数学形态学的传动系统振动信号处理

Vibration Signal Processing for Transmission System based on Quantum-inspired Mathematical Morphology

针对数学形态学中传统结构元素无法自适应调整高度的缺陷,引入量子理论提出了用于腐蚀算子的合成量子启发结构元素(compound quantum-inspired structuring element for erosion,CQSEE),用于提取机械传动系统振动信号的故障信息。CQSEE借助量子理论描述噪声和故障信息,在计算过程中充分考虑了噪声和故障信息的不同特点,实现了结构元素高度的动态调整。应用CQSEE分析滚动轴承故障信号,结果证明CQSEE提高了腐蚀算子的形态学分析能力。

Aiming at the disadvantage that conventional structuring element for the mathematical morpho- logical cant adjust its height adaptively, the quantum theory is employed to propose compound quantum -in- spired structuring element for erosion （ CQSEE）, which is used for extracting fauh information in vibration sig- nal from mechanical transmission system. Since CQSEE utilizes quantum theory to depict noise and fault infor- mation, it maturely considers different characteristics of noise and fault information during computational process, which realizes the goal of adjusting height of structuring element dynamically. Then CQSEE is applied to analyze the fault signal of rolling element bearing. The result reveals that CQSSE improves the morphological ability of erosion operator.
