Vibratiion Analysis on truck frame of railway vehicle considering its flexural rigidity

摘要

Car body and trucks of lightweight high-speed train tend to vibration in elastic modes at fre- quencies higher than about 5Hz, and sometimes their flexural vibration leads to the deterioration of the riding comfort. This paper presents a theoretical analysis on the vibration of a truck frame and a car body with flexural rigidity. The vibrations induced by vertical track irregularities are analysed using the transfer matrix method. Numerical results are compared with results of measurements made on the Shinkansen train.
