摘要: 通过分析一个简化的履带车辆单扭力轴-负重轮力学模型,建立了扭力轴扭转角与路 面不平度的联系方程,基于该方程可以由路面不平度求出扭力轴扭转角,如已知扭转角则可 以通过逆动力学分析得到路面不平度. 数值算例结合ADAMS仿真结果验证了该方法用于路面 不平度测试的可行性.

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.
