【摘要】：由行驶车辆冲击造成窨井盖周边路面的松散破坏,会影响交通安全和增加道路维护成本。针对这一问题提出了一种带有颗粒阻尼器的减振型窨井盖,研究了该新型窨井盖的冲击减振特性。首先设计出带有颗粒阻尼器的新型窨井盖结构;其次理论探讨了新型窨井盖的结构耗能机理和影响参数;最后通过实验来研究新型窨井盖的冲击减振特性。结果表明带有颗粒阻尼器的窨井盖具有较好的冲击减振特性,颗粒阻尼器的阻振体尺寸、颗粒大小和填充率对窨井盖的冲击减振特性都有较大的影响,这为新型减振窨井盖的进一步优化和工程应用提供了有益指导,同时也为延长路面破损周期和降低道路维护成本提供了新的思路。
[Abstract]:The loose destruction of the pavement surrounding the cover of the well cover caused by the driving vehicle impact will affect the traffic safety and increase the cost of the road maintenance. In this paper, a kind of vibration - scenting cover with a particle damper is put forward, and the shock absorption characteristics of the new type of manhole cover are studied. Secondly, the energy dissipation mechanism and the influence parameters of the new type of manhole cover are discussed in theory. Finally, the shock absorption characteristics of the new type of manhole cover are studied by experiments. The results show that the scenting cover with particle dampers has good shock absorption characteristics, the size of the damper body, the size of particle and the filling rate of the particle dampers reduce the impact of the cover. The vibration characteristics have great influence, which provides useful guidance for the further optimization and engineering application of the new type of vibration control manhole cover. It also provides a new way of thinking for prolonging the pavement damage cycle and reducing the cost of road maintenance.
