Praćenje stanja konstrukcije kod složenih inženjerskih konstrukcija
Structural health monitoring of complex engineering structures
Vojnotehnički institut - VTI, Beograd
Ključne reči: praćenje stanja konstrukcije; inženjerske konstrukcije; metode bez razaranja; korišćenje senzora; primeri primene
Sažetak
U radu se razmatraju metode za praćenje stanja konstrukcije. Dve metode su detaljno obrađene. Prva metoda se zasniva na promenama frekvencije odziva, koje nastaju kao rezultat promena mase i frekvencije izazvane konstrukcionim oštećenjima. Druga metoda je zasnovana na promenama na širenju talasa. Pokazano je da će praćenje stanja konstrukcije može imati jak uticaj na konvencionalno održavanje i filozofiju održavanja, kao i na njihove procese. Prikazano je nekoliko primera praćenja stanja konstrukcije.
Abstract
This paper deals with methods for structural health monitoring. Two methods are presented in detail. The first one is based on changes on frequency response, which occurs as result of the mass and rigidity changes due to the structural damages. The second one is based on changes on wave propagation. It has shown that the structural health monitoring will have a strong impact on conventional design and maintenance philosophies and processes. Some examples of structural health monitoring applications are presented.
