摘要
针对水泥混凝土路面抗滑性能缺乏定量分析和合理评价方法的问题,采用有限元分析方法,对轮胎与水泥混凝土路面摩擦接触状况进行了数值模拟,分析了荷载、路表构造、胎压和行车速度等因素对轮胎与路面附着系数的影响。结果表明:荷载、刻槽宽度和槽间距均对路面附着系数影响显著,而刻槽深度几乎对路面附着系数没有影响;轮胎的充气压力越低,轮胎与路面之间的附着系数越大;车速越快,附着系数越小,并由此回归出路面附着系数与充气压力、荷载、行车速度以及路面构造参数之间的关系式。
For the lack of quantitative analysis and reasonable evaluation methods on skid-resistant performance of cement concrete pavement,this paper adopts the finite element method to simulate the frictional contact condition between tire and cement concrete pavement and then analyzes the impact of load,pavement surface structure,tire pressure,speed and other factors on adhesional coefficient between tire and pavement.The results indicate that： the load,groove width and groove space significantly affect adhesional coefficient,but groove depth has hardly effect on adhesional coefficient;the lower the inflation pressure of tire,the greater the adhesional coefficient between tire and pavement is;the faster the speed,the smaller the adhesional coefficient is.At last,the relationship among pavement adhesional coefficient and inflation pressure,load,speed,and surface structure parameters is acquired.5 tabs,7 figs,10 refs.
