But the longitudinal dynamics behavior of wheelset is often neglected while carrying out railway vehicle dynamics analysis.
但是机车车辆动力学研究中，对轮对的纵向动力学特点的研究往往被忽略。
Due to the interaction between railway Bridges and CWR, the longitudinal forces of CWR are passed to the piers through the structure of the bridge.
桥上无缝线路的纵向力，由于梁轨相互作用，将通过桥跨结构传递到桥梁的墩台上。
Temperature fields and longitudinal temperature stresses of Jiujiang Yangtze Railway Bridge obtained with this program are very agreeable to those obtained through practical measuring.
该程序计算出九江大桥的温度值及温度应力同相应实测值十分吻合。
