摘要:
针对城市道路行驶工程卡车引起周围地面振动问题,引入路面不平整函数,建立工程卡车的七自由度运动模型方程;利用FlexPDE软件求解出车轮激励,并施加于道路土体有限元模型上;在此基础上,研究了车辆引发地面振动的传播规律,并讨论车速、载重、路面特性对周围地面振动的影响。结果表明:近振源范围内,地面竖向和横向振动衰减速率明显高于远振源区城;速度和载重的增大对地面振动影响显著;随着路面不平整波长的提高,地面振动响应往往会降低。
Abstract:
The vibration of the ground caused by engineering trucks on urban roads was explored. Firstly, the function of road roughness was introduced, and the vehicle’s seven-degree-of-freedom equation of motion was established, then the FlexPDE software was used to solve the wheel excitation applied to the soil finite element model. On this basis, the propagation law of ground vibration caused by engineering trucks was studied, and the influence of vehicle’s velocity, load and road characteristics on vibration around the ground was discussed. The results showed that the ground vertical and transverse vibration attenuation rate in the near vibration source range were significantly higher than that in the far vibration source area. The increase of velocity and load had a significant impact on the ground vibration; as the uneven surface wavelength increased, the ground vibration response tended to decrease.
