Analysis of the Effect of Frequency Weighting According to the Sperling Index Method on the Dynamic Response of the Railway Vehicle Carbody to Vertical Vibrations by Ioana Izabela Apostol, Mădălina Dumitriu, Traian Mazilu

“…This model considers important elements that can influence the vertical vibration behavior of the carbody, namely, the carbody structural flexibility, which is represented by an equivalent Euler–Bernoulli beam, the system through which the longitudinal forces are transmitted from the bogies to the carbody, and the elasticity of the wheel–rail contact. Based on the analyses developed in the paper, the relevant conclusions regarding the effect of the frequency weighting functions specific to the Sperling index method on the dominant vertical vibration modes of the carbody are synthesized. …”

A Numerical Study of the Screening Effectiveness of Open Trenches for High-Speed Train-Induced Vibration by Chih-hung Chiang, Pei-hsun Tsai

“…A considerable increase in screening effectiveness of the open trench was observed from 30 to 70 Hz, which matches the main frequencies of vibration induced by Taiwan High Speed Rail. The influence of trench width on screening effectiveness is nonsignificant except for frequencies from 30 to 40 Hz. …”
