| 摘 要： | 轨道不平顺的速度项对车桥动力响应的影响，在以往车桥耦合振动分析中往往被忽略．首先阐述轨道不平顺速度项的概念和求解方法，然后对是否考虑轨道不平顺速度项所产生车桥振动响应的结果进行了分析比较．结果表明，两种计算差别比较显著，考虑轨道不平顺速度项的分析结果与实测数据更为接近．

| Abstract: | Track irregularity coupling with velocity of the vehicle(TICVV) influences the dynamic response of vehicle-bridge,which,however,was often ignored in previous studies.In this paper,the concept and the solution procedure of the TICVV are expatiated.Comparison shows that when the factor of TICVV is involved into consideration or not,the responses of vehicle-bridge coupling vibration are quite different.When TICVV is taken into consideration,the calculation results are closer to those from field test. |
