- 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.
