刚性路面道路刚度计算方法理论研究

Theoretical study on identification of the road stiffness of a rigid pavement

为实现坦克、装甲车及高档民用车辆在道路行驶中的主动减振控制,须对道路刚度参数快速计算。以温克尔地基模型为基础,据弹性地基板理论建立刚性路面道路计算模型,用刚性路面板挠度函数的半逆解法推导道路刚度理论计算公式。结果表明,该公式与精确解结果相比,误差小于其它理论公式与精确解结果误差,说明该公式具有较高的计算精度。

In order to achieve the active vibration control of tanks, armored vehicles and civilian premium cars during driving, the fast calculation of the road stiffness is of the first importance. Based on the Winkler foundation model, the calculation model for a rigid pavement was built according to the elastic foundation plate theory, and a theoretical formula for calculating the road stiffness of the rigid pavement was derived by using the semi-inverse method for the rigid pavement deflection function. The results of the examples show that comparing with the exact solution, the error of the theoretical formulas derived is smaller than that of other formula in literatures, and this theoretical formula has higher accuracy.
