Research On The Vibration Characteristic Of Multi-span Pipes

With the development of the society, the flow pipeline system is more and more widely applied in all aspects of the modern society. The vibration of fluid-structure interaction and the stability study of pipeline is becoming more and more important in the vibration process. This paper based on the transmission and reflection of the wave theory to explore the principle of vibration of multi-span pipes, provided a solution of vibration of multi-span pipeline.The research of this paper based on the vibration of pipeline[1,2], to study it we discuss it from several aspects.1. First of all the research of this part aimed at exploring the vibration of the pipeline of clamping on both ends, at this part we provide the function of single-span pipeline, and providing a calculation method of the critical flow velocity of single-span pipeline, and discussing some characteristics of the vibration process of single-span pipeline; then this paper focuses on several vibration problems of multi-span pipes to study, then obtain the vibration relationship of the two adjacent cross.2. In order to discuss this question we using the multi-span pipeline as the research object and apply the wave theory. We introduces the transmission function and reflective function of wave function in order to discussing this issue, then we study the vibration of every span pipeline and provide the wave function of every span pipeline, then to measure the vibration wave provide the solution to calculate the pipeline stress.3. At last this paper based on the real pipeline as the research object, to compare the date between the process of pipeline vibration and the theoretical models, then provide the relationship diagram between the individuals date. We Apply the relationship diagram to analyze the relationship of the various parameters to prove the validity of the theory. This paper summarizes the results of the pipeline vibration, at the same time discusses the design of pipeline and the attention about the process of transmission fluid, then provide my points about the future development of pipeline.
