Vold-Kalman filterEnergy entropyReal-time chatter detection is important in improving the surface quality of workpieces in milling. Since the process from stable cutting to chatter is characterized by the progressive variation of the vibration energy distribution, entropy has been utilized to capture ...

The Vold-Kalman filter allows for the high performance simultaneous tracking of orders in systems with multiple independent shafts. With this new filter and using multiple tacho references, waveforms, as well as amplitude and phase may be extracted without the beating interactions that are associated ...
【摘要】针对旋转机械启停车过程的振动信号具有非线性、非平稳的特性,提出Vold-Kalman阶比跟踪(Vold-Kalman Filter Based Order Tracking,VKF-0T)和能量分析相结合的一种故障诊断方法.分析旋转机械在发生故障时各阶比分量幅值的变化规律,通过Vold-Kalman阶比跟踪方法提取特定的阶比分量,以其能量与原信号总能量的比值...
A Vold鈥揔alman filter is proposed for decomposing the signal into periodic wheel and track related excitation鈥搑esponse pair functions. We demonstrate that these components are in turn correlated to operational conditions, such as wheel out-of-roundness and the rail type. We further illustrate ...
The algorithm uses the adaptive Vold-Kalman filter (VKF) to track the concerned order of disturbance and schedules the gain factors by calculating the ratio of predefined target amplitudes to the tracked disturbance amplitudes. The gain factors are used to tune the controller output of corresponding...
