【Abstract】 The root courses of pipe system vibration are very complicated, and vibration harm is various. Yet the testing and analysis of vibration for pipe system is far less strengthened than that for components. In this article, analyzed the harm and root courses of water & steam pressure piping system vibration, expounded the value of the vibration diagnosis and evaluation for the piping system. Introduced the technique route of vibration diagnose and vibration evaluation for piping system vibration, testing and analysis techniques and practice application. Finally, proposed the evaluation criteria for pipe vibration.更多还原
