| Abstract: | The pressures, positions and velocities of four cylinders of LPS-4000 hydraulic double-action tryout presses are controlled by computer, which sends out instructions to complete the whole press process according to the procedures predetermined. In the mean time, the real-time changes of stress and strain are also recorded by computer, which makes contributions to subsequent analysis and research of material performance. According to its functional characteristics, this paper puts forward one kind of control system which is based on Windows Control Center and S7- 400 Programmable Logic Controller. Moreover, the whole plan, control principle, constitution and function of the control system and its control strategy are illustrated too. |
