| 摘 要： | 为实现大型混凝土结构的温差自调节,文中在碳纤维布的电致发热效应的基础上,对碳纤维布混凝土梁在稳定功率输入下的温差、变形响应做了实验分析.在温差调节实验中采用变换供电功率的过程控制方式使得调节速度得到较大提高,并分析了在这种过程控制方式下功率变换的时间对温差调节快速性及稳定性的影响.

| Abstract: | To realize temperature self-adjustment of great concrete structure,based on the electrically induced heating effect of carbon-fiber textile,experimental analysis has been done for the responses of temperature difference and deformation of carbon-fiber textile concrete under invariable input.In the experiment of temperature adjustment,the process control by changing power is adopted which makes the speed of regulating increased greatly,and the influence of time for power changing on the speediness and stability of temperature adjustment is obtained by analysis. |
