| 中文摘要: |
| 采用二自由度四分之一汽车悬架和粘弹性地基梁模型建立了二维汽车 路面系统。通过模态叠加法得到了路面位移的显示解析解，研究了路面位移响应的分布规律及路面振动对汽车的二次激励作用。研究结果表明，汽车正在经过的路面振动最大，汽车行驶前后的路面振动不对称；路面对汽车的二次位移激励呈周期性分布，频率接近移动汽车载荷对路面的作用频率。 |
| 英文摘要: |
| A two dimensional vehicle pavement system is modeled with the two DOF quarter vehicle suspension and a beam on visco elastic foundation. Analytical solutions of vehicle body, wheel, and pavements dynamic response are derived by mode superposition method. The solutions are directed to analyze distribution of pavement displacement and compute the second road excitation to vehicle. It is found that the vibration of pavement where vehicle is passing is greatest and the pavement sections before and after vehicle vibrate asymmetrically; the second road displacement excitation is periodic and has a frequency near to that of moving tire loads acting on pavement. |
