Analysis of the time-variable operating stresses of reactor components. Pt. 2

There are various counting methods for frequency analyses of measured stress-time functions. The differences between these methods, their capabilities and limitations are discussed by means of an example. - It is often attempted to transfer the stresses measured at a certain location of a construction to other locations. This, however, necessitates that the vibration behaviour of the respective construction is known, as well as its influence on the stresses under consideration. The information which can be obtained by means of the correlation analysis is discussed for pressure pulsations during blowdown tests. (orig.)
