Multi-Task Data Imputation for Time-Series Forecasting in Turbomachinery Health Prognostics

Machines, 2022
Time-series forecasting is the core of the prognostics and health management (PHM) of turbomachinery. However, missing data often occurs due to several reasons, such as the failure of sensors. These partially missing and irregular data greatly affect the

Development of excitation test method for non-synchronous vibration of rotating turbine blade (Measurement of damping of non-synchronous vibration mode)

Nihon Kikai Gakkai ronbunshu, 2016
In order to analyze the blade vibration caused by flutter, it is necessary to understand both the aerodynamic damping and structural damping of the high vibration stress. Flutter Vibration mode occurring in the rated speed is non-synchronous mode.

Simple prediction method of unstable fluid force in turbine blade row of steam turbine

Nihon Kikai Gakkai ronbunshu, 2016
Unstable fluid force may be induced by rotor blade eccentricity in turbo machinery such as steam turbines. To develop a prediction method for unstable fluid force in turbine blade rows, we calculated the fluid force by using computational fluid dynamics (
