摘要
车辆载荷引起的振动问题 ,不仅带来了由高振动引起的环境问题 ,同时也是岩盐公路破坏的主要因素。采用单自由度车辆模型模拟在不平整路面上行驶车辆的轮载力 ,将其作为岩盐公路路基所受到的荷载 ,运用通用有限元分析软件 ANSYS对岩盐公路路基进行瞬态动力学分析 ,并用该模型对盐湖公路 K5 89左右一段进行了实例计算 ,将计算结果与实测结果进行了对比 ,以验证该数值分析方法的有效性。
The problems of vibration caused by vehicle loading not only result in the high vibrating environmental problems but also lead to the damage of the rock salt highway. In this paper, a single variance model of vehicle is adopted to simulate wheel load of the vehicle running on the uneven road surface, and the dynamic response of the roadbed is analyzed with the versatile software-ANSYS. This model is applied on around Sta. K589 of salt lake highway, and the calculated data is compared with the experimental result so as to validate this method.
