System Diagnostics for Harmonic Drive
Fault identification in mechanical power transmission systems, such as harmonic drives, is crucial for mechanical manufacturers. This project develops a fault detection technique to monitor the health of harmonic drive systems. A machine learning model is constructed to identify fault patterns by analyzing measured vibration signals.
Vibration Analysis of Satellite Structure
The development of low Earth orbit satellites has become a critical research area. One of the critical challenges during the satellite design phase is to prevent resonance vibrations at the vehicle launch stage. Therefore, it is important to establish an efficient modeling approach that can be integrated into the satellite design process. In this research, we apply the cyclic expansion method to analyze the modal property of a satellite structure. The resonance property of the system under harmonic and random excitation conditions are investigated.
Reduced-Order Modeling of Bladed Disk in Turbomachinery
Vibration analysis of bladed disks is computationally challenging due to complex geometry, mistuning, and nonlinearity inherent in the structures. Therefore, it is critical to develop efficient reduced-order modeling methods that can capture all of these factors. In this research line, efficient nonlinear modeling techniques are developed to enable analysis of high-dimensional finite element models of cyclic structures. Statistical analysis of bladed disks with mistuning and nonlinearities can be conducted efficiently.
