| 摘 要： | 目的 在弹性阶段对碳纤维混凝土(CFRC)条块试件施加荷载,得出荷载与相对电阻率变化率之间的关系.方法 通过改变加载位置、加载频率、加栽范围,测定荷载与试件电压之间的相互关系.计算得出相对电阻率变化率与电压之间的相互关系.通过曲线拟合,得出的曲线斜率反映压敏性的大小.结果 得出了条块的相对电阻率变化率与荷载的关系,相对电阻率变化率与荷载近似呈线性关系,通过拟合,斜率K的绝对值为0.316 9.在相同荷载作用下,改变加载速度和加载位置对条块的相对电阻率变化率影响不大.结论 碳纤维混凝土条块具有较好的压敏性.荷载与相对电阻率变化率近似呈线性关系,从而可实现动态称重.

| Abstract: | The objective is to find the relationship between relative changing rate of electric resistance rate and the load which is in the elastic range of CFRC cuboids.The voltage under load is measured with the change of loading position,loading frequency and loading range.After fitting,load-electric voltage is obtained,and absolute value of slope K is 0.3169.According to the experiments,the line reflects the amount of compressive sensitivity.The relationship between relative changing rate of electric resistance r... |
