Abstract

Abstract

On the basis of the solution for dynamic equilibrium equation utilizing the Newmark method, the formulas for calculating vibration load were derived, the dynamic finite element method for calculating vibration-load history using the measured vibration-acceleration history was put forward. Combined with the vibration-acceleration history of the field measurement in Qinhuangdao-Shenyang dedicated passenger line, the vertical vibration-load history curves were calculated when train speeds were 230 km/h and 265 km/h. It is pointed that the maximum vertical vibration load increases by 16.34 kN when train speed increases by 35 km/h. The results indicate that vibration-load history could be obtained with the measured vibration-acceleration history, the method is feasible.
