Experiment Research And Finite Element Simulation Of Piping

Due to the flexibly and randomness of piping , the mechanism of penetration deformation is in great dispute. The complex interactions between water and soil in the process of piping proves that the piping develops and changes with the time. This is a nonlinear dynamic process, there is no generally accepted theory with the most appropriate method. So, use of electronic cameras in a micro-perspective way and the Finite Element Theory to discuss the development and formation of piping has a great significance.This article summarizes and concluded from the research of the predecessor, carried on with a model experiment, made a detailed description and a summary of the basis of experimental data for the analysis and interpretation of the phenomenon, and according to the experiment result, gives some exploration about the phenomenon, through the finite element description of the basic tenets and the demonstration of the similarity between the temperature field and seepage, use the large-scale finite element analysis software ANSYS as the platform to analysis the seepage problem. The main work includes:(1) Collect large amount of related research. which mainly include the infiltration and sabotage piping and piping mechanism of the two tests and numerical model, in the piping based on the current situation at home and abroad are reviewed.(2) Carried on with a model experiment, made a detailed description and a summary of the basis of experimental data for the analysis and interpretation of the phenomenon, and according to the experiment result, gives some exploration about the phenomenon.(3) From the basic theory of the penetration deformation, the finite element analysis gave a detailed exposition of the basic tenets of seepage. Temperature and seepage under the similarity, Research on the use of large-scale finite element analysis software ANSYS calculating the thermal analysis of the piping seepage. To clarify the calculation of the basic steps to determine the solution of seepage, flow velocity and penetration than landing approach.(4) Use the Temperature analysis function in ANSYS, analysis the Uniform, isotropic seepage under the experiment. Based on experiment 1 and experiment 8, gives the detailed result. And carried on the comparison confirmation to the result.Finally , carried on the brief discussion about the direction of working further.
