Design of steel anti-stretching load acquisition device with CAN bus;

基于CAN总线的钢筋抗拉荷载采集器设计

In this paper,load value of hydraulic pressure testing machine was acquired by using photoelectric encoder and AT89C52 microcontroller,and steel anti-stretching load was discriminated by means of analyzing the time-load curve.

利用光电编码器和AT89C52相结合采集液压试验机的荷载值,通过实时分析时间荷载曲线来判别钢筋的抗拉荷载,并利用SJA1000控制器将试验结果上传至CAN总线数据服务器。

In this paper,three group of tests including overlapped jointing,jointing with or without full welding line in the bent arc for 25Ⅱ jointing reinforcement bars were carried out to evaluate the tensile strength of the 25Ⅱ jointing reinforcement bars,according to the data acquired.

完成了包括2 5Ⅱ级钢筋搭接焊、弯折 90°对焊焊缝不填满弯折圆弧处 ,以及弯折 90°对焊焊缝填满弯折圆弧处三种情形对应的三组结构抗拉承载力试验 ,试验数据表明 ,2 5Ⅱ级钢筋搭接焊、弯折 90°对焊焊缝填满弯折圆弧处不会降低2 5Ⅱ级钢筋焊接结构的抗拉承载力 ,弯折 90°对焊焊缝不填满弯折圆弧处将使2 5Ⅱ级钢筋焊接结构抗拉承载力大大降低 ,本文基于大型结构分析软件ANSYS的非线性有限元分析结果亦验证了如上结论。
