| 摘 要： | 考虑桥面凸凹不平，把路面粗糙度随机变化的状况转化为功率谱函数，建立纵向分布函数，提出新的路面平整度模拟办法。基于大型有限元计算软件ANSYS／LS～DYNA，分剐对车与桥梁建立实体模型，考虑两者在运动过程中的接触碰撞来模拟车与桥的互相作用，阐述车桥耦合影响。

| Abstract: | Random changes of deck roughness are transformed into power spectrum function while sags and crests on bridge deck are taken into consideration, and longitudinal distribution functions are established to put forward new simulation method for deck planeness. In the paper, physical models for vehicles and bridge are established respectively one the based of the large-size finite element computation software ANSYS/LS-DYNA, and the interaction between vehicles and bridge is simulated in motion by considering their touch and collision so as to expatiate vehicles-bridge coupling influences. |
