tar-paved造句

• Third , mensurated the front axle ' s load - time history when truck was running on general tar - paved roads , mountainous roads and the proving ground enhancement roads , second sampled and pretreated to the load - time history with rpc software of mts corporation , acquired the relationship of the frequence of the mean and amplitude load , obtained the zero mean equivalent loads using goodman experiential fatigue equation , acquired the weibull distributing functions of equivalent loads of respective roads
  第三，测定了汽车前桥在一般沥青公路、山区公路和试验场强化试验路面的载荷时间历程。对载荷时间历程进行了二次采样和数据预处理。采用雨流计数法得到了各路面的载荷均、幅值的频次关系，并根据goodman经验疲劳公式，得到了零均值的等效载荷及相应的频次。
• Fourth , according to the weibull distributing functions of equivalent loads , calculated the max loads by expanded sample method , acquired eight routine loads spectrum of each roads taking advantages of the connover classification method , calculated the respective enhancement coefficient in principle of amended miner linear accumulated fatigue damage rule , by the comparative norm of general tar - paved road , educed the mathematical model of calculating enhancement coefficient of synthesized roads
  利用数理统计的方法得到了各路面的等效载荷的weibull分布函数。第四，根据各路面的等效载荷的weibull分布函数采用扩展样本法求得了各路面的极值载荷，按照connover的分级法得到了各路面的八级程序载荷谱。以一般沥青公路为比较基准，采用修正的miner线性累积损伤理论，根据前桥的s - n和p - s - n关系式得到了各路面的强化系数，建立了综合路面的强化系数计算的数学模型。
