uneven speed

The model in time domain of road random disturbance to a vehicle with uneven speed is used to study the coupled vibration of an elastically supported beam and a vehicle with uneven speed and to establish the dimensionless motion differential equations.

应用车辆非匀速行驶时路面随机激励的时域模型,研究了非匀速车辆与弹性支承桥梁耦合系统并建立了其无量纲运动微分方程,获得桥梁跨中的无量纲最大挠度、车辆的舒适度随路面不平度系数、车辆的加速度及前后轮激励相关性的变化规律。
