| Summary: | 碩士 === 國立臺灣海洋大學 === 系統工程暨造船學系 === 104 === This thesis is to discuss the simulation for transfer mobility of a pile with damping material. Establish sandwich piles with different damping thickness by ABAQUS. Simulation the pile withstand a unit force at the pile of edge, take the middle of the pile transfer mobility data.
First, it used three piece of plates (base plate, sandwich of damping layer thickness 1mm and 3mm) experimental measurement (modal analysis, transfer mobility) and collocation parameters of material properties in this thesis. Then to compare experimental data of transfer mobility to ABAQUS data of transfer mobility within the error range within ± 3dB.
Then, pile the sandwich model with material parameters of the test result. Simulation pile of different damping layer thickness of the transfer mobility function.the pile pipe and compare its additional drop different layer thicknesses of the vibration damping effect. In addition to the larger the amount of deformation of the site for an additional damping layer. Analysis results can be understood when only the addition of damping material pile pipe for the middle part, its damping effect as poor. When the damping material in contact with the ground, its damping effect as good. And want to reduce the amount of axial vibration of pile pipe need to use a thicker layer of damping, results of its analysis of the damping layer thickness of 10mm, transfer mobility of axial have reduced.
