Vibration and Noise Reduction Design of Particle Damping Technique of High-speed Rail Floor Profiles
摘要
Abstract
The increase of the speed of high-speed trains makes their vibration and noise problem more and more seri-ous,and the floor profile of high-speed train,as an important part of the vibration and noise transmission path,becomes the key of vibration and noise reduction design.Therefore,in this paper,the particle damping technique for the vibration and noise reduction design of high-speed train floor profiles was introduced.Firstly,the finite element model of the floor profile was established,and the modal analysis and harmonic response analysis were carried out,which provided the basis for the subsequent vibration reduction design.Subsequently,the appearance of the particle damper was designed and the discrete el-ement model of the particle damper was established.And then,the influence of different particle damper configuration pa-rameters on the system energy consumption was analyzed through the discrete element model to obtain the optimal particle damper configuration parameters.The simulation results were verified by conducting excitation experiments.It is shown that the experimental effect is consistent with the trend of the simulation effect,which proves the effectiveness of the discrete ele-ment model.Finally,the optimal configuration of the floor profile installation of the particle dampers was given for sound in-sulation experiments,and the experimental results were good,which proves the effectiveness of particle dampers for the floor aluminum profiles and provides good engineering application prospects.关键词
