Title The design of the control section of impact dynamic
parameters measurement system
Abstract The dynamic testing system for parameters of hammer impact can do the test of mechanical and technological properties of various kinds of metal and nonmetal.
This graduation design focus on the design of of impact dynamic parameters measurement system，according to the overall program requirements. Stepper motor and the control system of stepper motor is introduced. According to the actual situation, I choose the AT89C51 to be the most important part of the hardware. I choose the SH-30806 as the driver of the stepper motor. This thesis focus on the design of the hardware of dynamic testing system for parameters of hammer impact and the software design. After the user set the height on the LCD, the stepper motor decline automatically to the bottom and suck the hammer, then rise to the setted height. It is prepared for the test. After the experiment of the system, the results meet the requirement.
Keywords: parameters of hammer impact the section of control
