Abstract

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

Key words
