Through the study on the vibration characteristics of the typical pipe, it tries to provide the basis for the pipe design and the pipe ground test method. A typical pipe is selected. First, modal analysis is carried out through theoretical analysis and finite element simulation. Then, pipe vibration is studied by finite element simulation and test. The results show that the theoretical results in modal analysis coincide well with those in finite element simulation. The finite element simulation and experimental results are basically consistent in vibration analysis. The reason for the difference is mainly the ideal boundary of simulation. The combination of finite element simulation and test is an important method for the research of pipe reliability and environmental adaptability.
