Abstract. A high degree of accuracy in dimensioning and controlling
the safety from destruction can be reached by measuring exploitation load
of the vital elements of the construction. The choice of the adequate load
spectrum is performed by introducing a number of representative spectrums
for particular operating conditions, each of these having its probability
of occurrence. The easiest way to solve the problem is to introduce the
standardised load spectrums with the aim of forming the catalogues of the
standardised load spectrums for representative mechanical systems.
PRORAČUN NOSIVOSTI ZUPČANIKA U NESTACIONARNO
PROMENLJIVIM EKSPLOATACIONIM USLOVIMA
Visok stepen tačnosti pri dimenzionisanju i provera sigurnosti protiv razaranja
može se postići merenjem eksploatacionih opterećenja vitalnih elemenata
konstrukcije. Izbor merodavnog spektra opterećenja vrši se uvođenjem više
spektara reprezenata za određene radne uslove pri čemu svaki od njih ima
svoju verovatnoću pojave. Problem se najlakše rešava uvođenjem normiranih
spektara opterećenja sa težnjom da se formiraju katalozi normiranih spektara
opterećenja za reprezentativne mašinske sisteme.
