The maximum impact energy of the equipment is 300J, and it is equipped with a 150J pendulum hammer.

Protocol Description

The working principle of the equipment is to use the high-precision photoelectric encoder and the computer with special measurement and control and computing software to detect the impact absorption work and the impact toughness of the material by detecting the difference between the impact and after the impact of the pendulum. The display mode is double explicit: that is, the dial pointer and the computer display at the same time. Computer can show shock absorption work, impact toughness, and can test data automatic processing, automatic generation test report, pendulum, return, impact, pendulum action control can be controlled by manual box, can also use the computer program automatically control by the mouse input, and can batch or successive print test results.

The equipment uses Panasonic PLC as the lower computer control, the brand computer as the upper computer control, the upper computer program adopts VB programming, RS232 communication mode, to complete the data exchange and instruction transmission of the upper and lower computer, and make full use of the powerful functions of the PC for data processing, report processing, etc. The high-precision rotary encoder is used to obtain the real-time position of the pendulum and obtain the shock absorption work. It has the characteristics of system reliability, stability and accurate data.
