- a detecting device is provided beside the lock cylinder 424 for judging whether the hook 423 is in place. If the hook 423 is not in place, the lift motor 40 will not be raised to the side of the lifting hammer device 2. Running.
- the dynamic performance test system of the present invention includes a human-machine interface, a programmable controller (PLC), a frequency converter of the lift motor 40, a signal input end, and a signal output end to control the falling hammer test process. Work properly.
- PLC programmable controller
- the signal input at the signal input terminal may include a drop height selection, a secondary strike selection, a fence state, a drop drop state, a hook state, a drop hammer switch state, a displacement count obtained by an encoder, etc., and a signal output terminal output.
- the signal may include a drop hammer preparation lamp signal, a drop hammer enable signal, an optical alarm, an acoustic alarm, an anti-secondary strike signal, a frequency converter operation signal, a frequency converter stop signal, and the like.
- the human-machine interface can be a touch screen, and the touch screen displays the language selection screen.
- the user can select a simplified Chinese character or an English (ENGLISH) screen: Once the screen is selected, the user cannot switch without re-powering, switching from the Chinese character interface. Switch to the English (CHINESE TO ENGLIS) interface or switch from the English interface to the Chinese character interface (ENGLISH TO CHINESE). You must turn off the power and re-power it to select.
- the man-machine interface also has the "Test" option: It is a function option for checking whether the three electromagnets of the secondary strike and the drop hammer are normal. The user does not need to enter during the normal test. Exit in the debug screen.
- Lifting height (Hight) The height of the drop hammer device 2 is displayed by incremental rotary encoder measurement when the user correctly determines the zero position;
- Pre-hight Enter the required lifting height through the touch screen, the system can automatically run to this height, and the user can fine-tune the position by jogging;
- Weight Based on the mass of the base hammer and the quality of the weight selected by the user, you can choose to increase or decrease the weight ⁇ .
- the sensing device includes at least a load cell disposed on the tray and sensing real-time impact data of the tray when the drop device is vertically dropped;
- the load cell can be a YFF-2 impact force sensor.
- Sensing device It can also include the KS60 displacement sensor, the strain gauge as the strain gauge sensor, the DLF-4 type multi-function charge amplifier, and the INV3018A data acquisition unit as a data acquisition module. The signals collected by each sensor are sent to the INV3018A data acquisition instrument and then to the control module and analysis module.
- the YFF force sensor is a piezoelectric quartz crystal sensor. It consists of two sets of quartz crystal plates, electric sheets, force plates, shells and sockets, which are circular.
- the YFF force sensor has a high resolution and can measure changes as small as 0.025N under large initial load conditions.
- the surface of the quartz crystal piece When the external force to be measured uniformly acts on the bearing bearing surface, the surface of the quartz crystal piece generates a charge proportional to the external force, is received by the conductive piece, and is connected to the charge amplifier through the connecting wire to output a proportional voltage signal.
- the YFF series sensor is a conversion device that converts "force” into “charge” by using the longitudinal piezoelectric principle of a quartz crystal.
- the charge generated by the sensor is proportional to the external force being measured.
- the charge is proportionally converted into a voltage by a charge amplifier, and the magnitude of the measured force and its change are directly read by a display or recorder.
- the YFF force sensor is disposed on the lower surface of the tray 61.
- the sensing points can be distributed on the same circumference and spaced 90 degrees apart
- the output of the output module has two main aspects, one is the output of the test result, and the other is the output of the test intermediate data.
- the test results can be output through the monitor and stored in the hard disk of the computer or output via an external display. For testing intermediate data, it can also be output in real time through a computer monitor and an external display.
- the main technical indicators of the dynamic performance test system of the present invention can be:
- Specimen size 2.5 ⁇ ⁇ 32, sampling space: 500mm, maximum impact energy: 15000J, total mass of hammer: 1000kg; basic hammer mass: 840kg, weight of 4 pieces, 40kg per piece, effective use height range: 0-1.5m, lifting height linearity: 0.5% (with cable encoder), lifting speed: 0 ⁇ 3m/min stepless adjustable, host height: about 4.5m, host height space: about 5.5m, host footprint Area: about 3mX 3.5m.
- Preparations include the following steps:
- the touch screen displays the language selection screen.
- the user can select the simplified Chinese characters or English (ENGLISH) screen, for example, select the Chinese interface.
- the starting speed should not be set too fast, and it is best at around lOOmm/s.
- the system can automatically run to the height by inputting the required lifting height through the touch screen, and the user can fine-tune the position by jogging.
