چکیده
Анализ чувствительности вибрационного метода структурной идентификации Я. П. Аузиньш, А. Ф. Бойко Рижский технический университет, Рига, Латвия Проанализирована точность определения свойств материалов элементов конструкций (мо дуль упругости, коэффициент Пуассона, плотность и др.) методом измерения частот собственных колебаний. Оценены точность определения частоты методом Фурье и влияние ее на конечный результат. С помощью метода метамоделей выведены зависимости между ошибками измерения частот и ошибками идентифицируемых параметров. Метод проил люстрирован на примере элемента обшивки с ребром жесткости.

Experimental and finite-element free vibration analysis and artificial neural network based on multi-crack diagnosis of non-uniform cross-section beam
Crack identification is a very important issue in mechanical systems, because it is a damage that if develops may cause catastrophic failure. In the first part of this research, modal analysis of a multi-cracked variable cross-section beam is done using finite element method. Then, the obtained results are validated usingthe results of experimental modal analysis tests. In the next part, a nove...
متن کاملA NEW APPROACH BASED ON FINITE ELEMENT MODEL UPDATING FOR STRUCTURAL DAMAGE IDENTIFICATION
In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...

In this paper, a structural damage identification method (SDIM) is developed for plate-like structures. This method is derived using dynamic equation of undamaged/damaged plate, in which local change in flexural rigidity is characterized utilizing a damage distribution function. The SDIM requires to modal data in the intact state and frequency response of damage state where most of vibration ba...
