摘要
应用广义有限积分变换和改进的Ｓｔｒｕｂｌｅ渐进方法，建立了汽车荷载通过柔性道口铺面板的计算模型，研究车辆通过道口铺面板的动态响应。着重讨论车辆轴重、速度的改变对道口板的竖向位移、竖向加速度和水平应力的影响。分析这种变化的特征以及发展趋势。
To study dynamic response of the soft grade crossing surface from the loads of automobile,a theoretical model of the grade crossing plate under moving masses is developed by basing on the modified generalized finite integral transforms and the modified Struble's method.In this paper, it is mainly discussed that changes of the vehicle weight and vehicle speed affect the vertical displacements,vertical accelerations and horizontal stresses of the grade crossing plate.The characteristic of these changes and their developing tendencys are analysed.
