A Sensitivity-Based Approach for Interval Reliability Analysis of Structures Under Random Excitation

Filippo Giunta, Giuseppe Muscolino, Alba Sofi
Proc. ASME. IMECE2021, Volume 7B: Dynamics, Vibration, and Control, V07BT07A052, November 1–5, 2021
Paper No: IMECE2021-71092
DOI: https://doi.org/10.1115/IMECE2021-71092
... Abstract The present study is devoted to the reliability analysis of linear discretized structures, with uncertain-but-bounded mass and stiffness parameters, subjected to stationary Gaussian multi-correlated random excitation. The reliability function for the extreme value stress process...

Operational Modal Analysis of a Rotating Structure Subject to Random Excitation Using a Tracking Continuously Scanning Laser Doppler Vibrometer via a Two-Dimensional Scan Scheme

Linfeng Lyu, Weidong Zhu
Proc. ASME. IMECE2021, Volume 1: Acoustics, Vibration, and Phononics, V001T01A040, November 1–5, 2021
Paper No: IMECE2021-71521

... laser spot on its surface. The measured response of the structure using the 2D scan scheme of the tracking CSLDV system is considered as the response of the whole surface of the structure subject to random excitation. The measured response can be processed by an operational modal analysis (OMA) method...
