Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, this utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As shown in Figure 1, this utility model embodiment provides pressures cycle fatigue pulse testing bench control system, including computer 1, embedded controller 2, proportional amplifier plate 3, hydraulic valve 4, pressure transducer 5, check valve 6, hydraulic pump 7, hydraulic electric motor 8, hydraulic oil container 9 and oil sump tank 10, computer 1 is connected with embedded controller 2, embedded controller 2 is connected with proportional amplifier plate 3 and pressure transducer 5 respectively, pressure transducer 5 is connected with hydraulic valve 4 and test block 11 respectively, hydraulic valve 4 is connected with oil sump tank 10 and check valve 6 respectively, check valve 6 is connected with hydraulic oil container 9 by hydraulic pump 7, hydraulic pump 7 is connected with hydraulic electric motor 8.
It should be noted that described hydraulic valve 4 is proportional pressure control valve.
Additionally, described embedded controller 2 includes main control unit, AD conversion module and D/A conversion module, main control unit is connected with AD conversion module and D/A conversion module respectively.
This detailed description of the invention computer acts primarily as supervisory function bit, realizes the control to embedded controller by human-computer interaction interface, and then controls the execution of whole hardware system. Embedded controller is made up of main control unit, A/D modular converter and D/A modular converter, and its effect is the operation that hydraulic system has been controlled being correlated with by the instruction accepting computer. Proportional amplifier plate selects the direct current amplification board supporting with proportional pressure control valve, can be considered scaling link. The inlet pressure of overflow valve is the test pressure of testpieces, and adopts this pressure signal of sensor acquisition. Hydraulic pressure executive item part is mainly used in performing the order that embedded controller is passed on, and operates accordingly.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
