Finite Element Analysis of Reducing the High-speed Railway Vibration Effect on the Environment Using Open Trenches
摘要
Abstract
The high-speed railway vibration effect on the environment has become more and more widespread in recent years,and technical measurements are needed to minimize the damage to the environment caused by this new transportation vehicle.It has been shown that open trenches can be used for this purpose because of their easy construction and relatively good isolation effects. The finite-element software ABAQUS was adopted to analyze the open trench isolation effects.In order to adequately absorb the shock wave and reduce the impact of border-reflected waves on the results,the infinite element and visco-elastic boundary is used in this model.The parameter ARF is introduced in the calculation procedure so as to evaluate the isolation effects.The reduction effect of different factors that influence the resulting vibration reduction,such as the different si-zes of an open trench and the frequency of the vibration load,are also discussed.The obtained ap-proaches can be applied by designers in this area.关键词
