Description
Summary:The presented examples show the possibility to obtain actual information on the stiffness distribution and constraint parameters of a piping system by a non-destructive method without demounting hangers. A strategy for model updating by means of ambient vibration analysis is being developed to determine the real constraints of a piping system quantitatively. Hereby the amplitude dependency of the hanger stiffness must be investigated carefully.
