高速鐵路振動荷載的模擬研究

梁波，羅紅，孫常新

摘要：高速鐵路路基動力響應的分布和變化規(guī)律已成為研究和解決路基問題的重要方面，通過確定動荷載來研究路基的動力特性是其中的一種方法。列車荷載是一個很復雜的問題，同時涉及列車軸重、懸掛體系、行車速度、軌道組成、線路平順等等因素。本文將在充分考慮振動荷載產(chǎn)生機理（車輛因素、軌下基礎因素等）的基礎上,對已有的列車荷載表達式進行修正和完善。修正后的表達式，既考慮了相鄰輪對間輪軌力的相互疊加和軌枕的分散作用，又考慮了由于軌道不平順所產(chǎn)生的振動激勵及其他要素，以期為高速列車動荷載的確定和路基動力響應分析提供借鑒和參考。

Vehicle-bridge interaction element for dynamic analysis

Yang, YB; Yau, JD

Abstract:The objective of this study is to develop an element that is both accurate and efficient for modeling the vehicle-bridge interaction (VBI) in analysis of railway bridges carrying high-speed trains, which may consist of a number of cars in connection. In this study, a train is modeled as a series of sprung masses lumped at the bogie positions and a bridge with track irregularities by beam elements. Two sets of equations of motion that are coupled can be written, one for the bridge and the other for each of the sprung masses. To resolve the problem of coupling, the sprung mass equation is first discretized using Newmark’s finite difference formulas and then condensed to that of the bridge element in contact. The element derived is referred to as the vehicle bridge interaction element, which has the same number of degrees of freedom (DOF) as the parent element, while possessing the properties of symmetry and bandedness in element matrices. For this reason,conventional assembly procedures can be employed to forming the structure equations. The applicability of the VBI element is demonstrated in the numerical studies.

Position-based modeling for wireless channel on high-speed railway under a viaduct at 2.35 GHz

Liu, Liu; Tao, Cheng; Qiu, Jiahui; et al.

Abstract:This paper presents a novel and practical study on the position-based radio propagation channel for High-Speed Railway by performing extensive measurements at 2.35 GHz in China. The specification on the path loss model is developed. In particular, small scale fading properties such as K-factor, Doppler frequency feature and time delay spread are parameterized, which show dynamic variances depending on the train location and the transceiver separation. Finally, the statistical positionbased channel models are firstly established to characterize the High-Speed Railway channel, which significantly promotes the evaluation and verification of wireless communications in relative scenarios.

Challenges toward wireless communications for high-speed railway

Ai, Bo; Cheng, Xiang; Kuerner, Thomas; et al.

Abstract:High-speed railway (HSR) brings convenience to peoples’ lives and is generally considered as one of the most sustainable developments for ground transportation.One of the important parts of HSR construction is the signaling system, which is also called the “operation control system,” where wireless communications play a key role in the transmission of train control data. We discuss in detail the main differences in scientific research for wireless communications between the HSR operation scenarios and the conventional public land mobile scenarios. The latest research progress in wireless channel modeling in viaducts, cuttings, and tunnels scenarios are discussed. The characteristics of nonstationary channel and the line-of-sight (LOS) sparse and LOS multiple-inputmultiple-output channels, which are the typical channels in HSR scenarios, are analyzed. Some novel concepts such as composite transportation and key challenging techniques such as train-to-train communication, vacuum maglev train techniques, the security for HSR, and the fifth-generation wireless communications related techniques for future HSR development for safer, more comfortable, and more secure HSR operation are also discussed.

Dynamic analysis of railway bridge under high-speed trains

Xia, H; Zhang, N

Abstract:The dynamic interaction between high-speed train and bridge is studied by theoretical analysis and field experiment. A computational model of train-bridge system is established. Each vehicle is described by 27 degrees of freedom. The bridge is modeled by modal superposition technique. The measured track irregularities are taken as the system excitation. The whole histories of the China-Star high-speed train running through a bridge with 24 m-span PC box girders on the Qin-Shen Special Passenger Railway in China are simulated. The dynamic responses of the bridge such as dynamic deflections, lateral amplitudes, lateral and vertical accelerations, lateral pier amplitudes, and the vehicle responses such as derail factors, offload factors, wheel/rail forces and car-body accelerations are calculated. The proposed analysis model and the solution method are verified through the comparison between the calculated results and the in situ measured data.

Dynamic analysis of high speed railway bridge under articulated trains

Xia, H; Zhang, N; De Roeck, G

Abstract:The problem of vehicle-bridge dynamic interaction system under articulated high speed trains is studied in this paper. A dynamic interaction model of the bridge-articulated train system is established, which is composed of an articulated vehicle element model and a finite element bridge model. The vehicle model is established according to the structure and suspending properties of the articulated vehicles. A computer simulation program is worked out. As an example, the case of the Thalys articulated train passing along the Antoing Bridge on the Paris-Brussels high speed railway line is analyzed. The dynamic responses of the bridge and the vehicles are calculated. The proposed analysis model and the solution method are verified through the comparisonbetween the calculated results and the in situ measured data. The vibration behaviour of the articulated trains is discussed.

An empirical path loss model and fading analysis for high-speed railway viaduct scenarios

He, Ruisi; Zhong, Zhangdui; Ai, Bo; et al.

Abstract:Based on the narrowband 930-MHz measurements taken along the “Zhengzhou-Xi’an” highspeed railway in China, an empirical path loss model is proposed. It is applicable to high-speed railway viaduct scenarios, considering the influences of viaduct height H and base station antenna relative height h, which are not well-covered by existing large-scale models. The path loss exponents are investigated, based on which the influence of viaduct on propagation is discussed. The fading depth up to 15.96 dB and the Ricean K-factor with mean value of 3.79 dB are obtained.

Abstract:The dynamic interaction between high-speed train and simply supported girders is studied by theoretical analysis and field experiment in this paper. The dynamic interaction model of the train-bridge system is established,in which the rigid-body dynamics theory, finite element method and wheel-rail displacement corresponding assumption are adopted for the vehicle model, bridge model and wheel-rail interaction model, respectively. The measured track irregularities are taken as the system excitation. The responses of a 24 m-span PC box girder bridge are calculated. The proposed analysis model and the solution method are verified through the comparison between the calculated results and the measured results.

Vibration of simple beams due to trains moving at high speeds

Yang, YB; Yau, JD; Hsu, LC

To investigate the vibration of simple beams subjected to the passage of high speed trains, a train is modeled as the composition elf two subsystems of wheel loads of constant intervals, with one consisting of all the front wheel assemblies and the other the rear assemblies.By an analytical approach, the key parameters that govern the dynamic responses of the beams are identified, using the moving load assumption. To evaluate the inertia effect of moving vehicles, numerical solutions are obtained using Newmark’s beta method. Based on the condition of resonance and the condition of cancellation for the waves generated by continuously moving loads on the beam,optimal design criteria that are effective for suppressing the resonant responses are proposed, In designing a high speed railway bridge, such criteria should be considered in selecting the span length and cross-section of the beam,given the car length, axle distance and operating speed of the train.
