本文利用激光诱导化学镀的方法制作电阻应变片,并将此应变片用于小位移量的测量.设计过程包含应变片的制作和位移测量电路的设计两个部分.应变片选择聚酰亚胺薄膜作为基底,涂敷AgNO3-PVP酒精溶液后利用激光诱导化学镀的方法在基底上刻出栅极,清洗后进行镀铜,最后引出电极并贴上保护覆盖层.位移测量电路设计主要是利用双臂电桥将应变引起的应变片电阻变化转化成电压的变化,再通过AD8221芯片将电压变化信号放大后进行测量.电路设计部分还包括电源模块和电压显示模块.最后通过千分尺对电路进行标定并给出位移与对应的电压的关系图.
实验结果表明应变片测量电路的设计是成功的,在一个较小的测量范围内能较准确的显示出位移的变化.
希望可以用自己的知识来翻译下,不要Google或者百度,这些地球人都知道,毕业设计很重要的
麻烦帮下忙,工作室啥的就算了
In this paper, laser-induced chemical plating method produced resistance strain gages and strain gages for measurement of small displacement. The design process consists of two parts of the production and displacement of the strain gauge measurement circuit design. Strain gauge polyimide film as the substrate, coating of AgNO3-PVP alcoholic solution using laser-induced chemical plating method to carve a gate on the substrate, cleaning copper, and finally leads to the electrodes and paste protection overlay. Displacement measurement circuit design is the use of the double bridge strain caused by the strain gauge resistance change into voltage changes, and then after AD8221 chip voltage change signal amplification measurements. Circuit design section also includes a power supply module and voltage display module. Finally, the micrometer calibration and gives the displacement and the corresponding voltage circuit diagram.
  Experimental results show that the strain gauge measurement circuit design is successful in a smaller measuring range can more accurately show the displacement changes.
