摘要:
为精准提取数控机床旋转机械设备故障信息,量化数控机床旋转机械运行路径偏离程度,提出一种基于 VMD 的旋转机械运行路径偏离故障检测方法。分析数控机床旋转机械设备运行频率和振动情况,运用突变检测算法优化采集效率,使用自适应脉冲法采样机械信号;创建约束变分模型,利用遗传算法搜索信号变量最优值,通过 VMD 法分离信号频域分量,提取机械信号故障特征;通过聚类法评估路径偏离水平,构建胶囊网络进行路径偏离故障检测,利用 squash 函数挤压处理胶囊矢量并提升矢量维度,运用特征编码和归一化处理获得高精度偏离故障检测输出值。实验结果表明,所提方法检测的数控机床旋转机械运行路径偏离故障效果较好,且检测效率较高。
Abstract:
In order to accurately extract the fault information of rotating machinery equipment of NC machine tools and quantify the deviation degree of rotating machinery running path of NC machine tools , a rotating machinery running path deviation fault detection method based on VMD is proposed.The running frequency and vibration of rotating mechanical equipment of NC machine tool are analyzed , the mutation detection algorithm is used to optimize the acquisition efficiency , and the adaptive pulse method is used to sample mechanical signals ; The constrained variational model is established , the optimal value of signal variables is searched by genetic algorithm , the frequency domain components of signal are separated by VMD method , and the fault characteristics of mechanical signal are extracted ; The path deviation level is evaluated by clustering method , and the capsule network is constructed for path deviation fault detection.The capsule vector is extruded by square function and the vector dimension is improved.The high-precision deviation fault detection output value is obtained by feature coding and normalization.The experimental results show that the proposed method has good effect and high detection efficiency.
