MODAL ANALYSIS AND VERIFICATION PERFORMED TO CYCLIC SYMMETRIC STRUCTURES BASED ON STOCHASTIC SUBSPACE IDENTIFICATION

Jixie qiangdu, 2016
To determine whether stochastic subspace identification（ SSI） based on the output-only measurements can identify the doublet modes of cyclic symmetric structures accurately,taking a brake disc as an example,modal analysis based on SSI and traditional ...

A Mixed Frequency BVAR for the Australian Economy*

Economic Record, Volume 102, Issue 337, Page 182-207, June 2026.
A mixed frequency vector autoregression (MFVAR) model is proposed for nowcasting, forecasting and backcasting Australian macroeconomic indicators at monthly and quarterly frequencies. A novel augmented Minnesota prior for MFVAR models is also introduced.

Modal Identification Method of Offshore Wind Turbine Tower Based on SSI and FSDPC

Shock and Vibration
The structural health monitoring of offshore wind turbine towers is critical for ensuring their operational integrity. The condition of the tower structure is characterized by its modal parameters, which serve as effective health indicators.

Application of Covariance Driven Stochastic Subspace Identification Method

, 2022
In this research the application of output-only system identification technique known as Stochastic Subspace Identification (SSI) algorithms in civil structures is carried out. With the aim of finding accurate modal parameters of the structure in off-line analysis, a stabilization diagram is constructed by plotting the identified poles of the system ...

Structural Health Monitoring of Steel Garage Model with Stochastic Subspace Identification–Covariance Variance Analysis

Buildings
Traditional methods of determining structural dynamic parameters produce destructive and unreliable results. Therefore, in this study, operational modal analysis method, which is a non-destructive and advanced method, was used to determine structural ...

Fast Multi-Order Stochastic Subspace Identifi cation

, 2010
Stochastic subspace identification methods are an efficient tool for system identification of mechanical systems in Operational Modal Analysis (OMA), where modal parameters are estimated from measured vibrational data of a structure. System identification is usually done for many successive model orders, as the true system order is unknown and ...
