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.

Vibration Analysis of Satellite Structure
The development of low Earth orbit satellites has become a primary focus for the nation. One of the critical challenges during the satellite structure design phase is to prevent resonance vibrations during the launch stage. Therefore, it is imperative to establish an efficient modeling approach that can be integrated into the design process. In this research area, we are working on creating reduced modeling techniques to facilitate modal analysis, harmonic analysis, and random vibration analysis for complex satellite structures.

System Diagnostics for Harmonic Drive
Fault identification for transmission systems, such as harmonic drives, is a crucial task for mechanical manufacturers. We are developing signal processing tools to facilitate efficient detection and classification of potential faults in harmonic drive systems. These faults can be identified by analyzing the vibration signals before the product leaves the factory.
