摘要
利用光栅尺精细刻度和位移检测探头的关系,设计方波脉冲发生电路来记录弹性模量,并用单片机进行数据采集和处理,同时在数码管上进行位移量的显示.本仪器的研制,使得弹性模量实验测量精度大大提高,操作更加快捷.
Using the relations of raster rule, fine graduation and displacement＇s detect probe, the paper designs the square waves pulse circuit in order to note the elastomeric modulus, also uses the SCM to collect and dispose datas, at the same time disaplay the displacements. The development of this instrument improves the experiment＇ precision of elastomeric modulus experiment greatly and makes the operation more shortcut.
