Abstract: A relational equation between the torsion angle of a torsion bar and the roughness of a road is obtained by analyzing a torsion bar road wheel dynamics model for a simplified tracked vehicle. Based on the equation, the torsion angle is calculated against the roughness of the road and vise versa. A numerical example combined with the ADAMS simulation verifies the feasibility of the method to calculate the roughness of a road upon the measured result of a torsion angle.
