摘要
结合平顺性开发中激励源的实际情况,通过对双轴运输车辆振动力学模型的计算推导,研究分析了对车轮质心垂向响应影响较小的车轮、悬架与车身等参数,提出了用基准样车车轮质心垂向响应的实测数据作为开发车型模型的强迫激励输入进行汽车行驶平顺性的仿真的方法,并试验验证了方法的正确可行性。
The effect of wheel, suspension and body parameters to vertical response of the wheel centroid was analyzed through calculating vibration mechanics model of double-axle and half vehicle. The method of using the benchmark testing data of the vertical response of the wheel center of mass as the force excitation input of ride performance simulation was proposed, and the method was validated.
