Design of Pressure Vessel Fatigue Test System Based on PLC

Student name：Yao Zongrui Class：200362

Supervisor：Li Kangkang

Abstract ：A pressure vessel is a closed vessel that can withstand pressure. The use of

pressure vessels is very wide, it has an important position and role in many departments such

as industry, civil, military and many fields of scientific research. In order to realize the design

of the pressure vessel fatigue test system based on PLC, the following work has been carried

out and completed:

Firstly, the development of pressure vessel and PLC and its research status at home and

abroad are summarized and analyzed, the design requirements of the test experiment are

clarified, the research background of the subject is outlined, and the significance of the study

of the subject is expounded.

Then, the basic theory and technology related to the PLC controlled pressure vessel

fatigue test experiment are sorted out, the principle scheme of the pressure vessel test platform

is conceived, and the main parameters of the experiment components are designed and

selected.

Then, the three-dimensional model of the main components of the pressure vessel test

bench (pressure sensor, solenoid valve, pressure vessel) is established, the parameter

coordination of each component of the pressure vessel test bench is realized, the PLC control

program is written, the touch screen display is designed, and the pressure vessel fatigue test

experiment simulation based on PLC and touch screen is realized.

Finally, the assembly structure of the pressure vessel test bench is designed, its three-

dimensional structure model is established, and the assembly drawing and the engineering

drawing of the main parts are drawn.

This paper has completed all the expected research contents, and its work can play a

certain role in the development of pressure vessel fatigue test experiment.
