摘要: 应用有限元数值计算方法,分析了复合路面在移动荷载下的动力响应问题.针对多层结构体系,建立了相应的有限元实体模型,并进行了动力响应分析.分别讨论了复合路面在不同车速的作用下的位移和应力变化.计算结果表明,车辆速度对路面的结构力学响应有较大影响,在路面设计和疲劳寿命设计中需要充分考虑振动和冲击载荷的影响. 更多还原

Abstract: The dynamic response question of composite pavement under moving load is analyzed by using the finite-element numerical calculation method.The finite-element entity model is built in this paper and the dynamic response analysis for sandwich structure is completed.The change of the stress and displacement of composite pavement under different vehicle speed is discussed respectively.The computed result shows that vehicle speed makes an important effect on structure dynamic response and the influen...
