متن کاملInnovative Method for Damage Identification and Structural Health Monitoring based on Vibration Measurements
The purpose of this paper is to present an innovative application within the Non Destructive Testing field based upon vibration measurements developed by the authors during these past four years at the Department of Aeronautical Engineering of the University of Naples “Federico II” (Italy). This proposed new method is based upon the acquisition and comparison of the Frequency Response Functions...
متن کاملBASIS PURSUIT BASED GENETIC ALGORITHM FOR DAMAGE IDENTIFICATION
In damage detection the number of elements is generally more than the number of measured frequencies. Consequently, the corresponding damage detection equation is undetermined and thus has infinite solutions. Since in the damaged structures most of their elements remain healthy, the sparsest solution for the damage detection equation is mostly the actual damage. In the proposed method, the dama...
متن کاملDamage Identification of Piles Based on Vibration Characteristics
A method of damage identification of piles was established by using vibration characteristics. The approach focused on the application of the element strain energy and sensitive modals. A damage identification equation of piles was deduced using the structural vibration equation. The equation contained three major factors: change rate of element modal strain energy, damage factor of pile, and s...
متن کاملRotation-based sampling Multi-Particle Collision Algorithm with Hooke-Jeeves for Vibration-based Damage Identification
The structural vibration-based damage identification can be formulated as an optimization problem. The objective functional is expressed by a least square difference between measured and computed forward model displacements. The latter functional is minimized by using a hybrid scheme combining Rotation-based sampling Multi-Particle Collision Algorithm with Hooke-Jeeves heuristic (RMPCA-HJ). Mul...
