| 摘 要： | 将双轴汽车多自由度模型简化成四自由度的平面模型,忽略了车轮部分质量及刚度的影响。把质量m的车身等效的分解为前后轴以及质心C上的三个集中质量m2f、m2r及m2c,这三个质量由无质量的刚性杆进行连接。分析在该模型下振动输入对车身垂直和俯仰运动的影响,重点研究在有阻尼情况下双轴汽车模型的偏频和振型分析。

| Abstract: | Simplify the model of double-axle vehicle with multi-degree of freedom to planar model with four-degree of freedom. Neglect the influence in tyre mass and stiffness. Distribute the body’s mass into three lumped mass on front, rear and barycenter equivalently, The lumped mass connected by massless rigid bar. Analysis the influence of vibration input on vertical and pitch motion of vehicle body, Focus on the offset frequency and oscillation mode of double-axle vehicle with damping, Explore the response of forced oscillation with damping. |
