Abstract
An urgent need exists to predict the stress of a piping system connected to scroll compressors. Predicting the stress of a piping system is a useful way to help reduce the cost of developing products consisting of a piping system and scroll compressors. To meet this need, we investigated two main factors used to predict piping stress: the excitation forces of the scroll compressors and the vibration response of the piping system. We calculated the excitation forces and validated the results experimentally and calculated the vibration response by using the excitation forces and a finite-element model of the piping system. The calculated stress values agreed well with experimentally measured ones.
