SR-100E Microcomputer Controlled Electronic Universal Testing Machine Vocational Education Equipment For School Lab Mechanical Experiment Equipment
Key description:
1. Main machine: This machine adopts double-space door structure, with upper space stretching, lower space compression and bending test. The speed control system is installed at the lower part of the worktable, and the Japanese Fuji AC servo motor with high speed precision, wide range and stable performance drives the ball screw pair (stable transmission and low noise) rotation through the synchronous toothed belt reduction system, and the ball screw The cross beam in the auxiliary drive drives the tensile auxiliary equipment (or auxiliary equipment such as compression and bending) to move up and down to realize the loading and unloading of the sample. This structure ensures that the frame has sufficient rigidity, and at the same time realizes efficient, stable and gapless transmission. The upper and lower beams and worktable of the main machine are processed by a whole steel plate through a large imported processing center, which is not cast to ensure the accuracy of the main machine. The upper and lower clamps use a universal joint device to prevent lateral forces from being clamped during the test and ensure the coaxiality of the test.
2. Electrical measurement and control system:
2.1 Adopt Japanese AC servo drive and AC servo motor of Fuji company, the performance is stable and reliable, with over-current, over-voltage, over-speed, overload and other protection devices. The speed regulation ratio can reach 1: 100,000.
2.2 It has protection functions such as overload, overcurrent, overvoltage, displacement upper and lower limit and emergency stop.
2.3 The original controller ensures that the testing machine can realize closed-loop control of parameters such as test force, sample deformation and beam displacement, and can achieve constant velocity test force, constant velocity displacement, constant velocity strain, constant velocity load cycle, constant velocity Deformation cycle and other tests. It can be smoothly switched between various control modes.
2.4 Equipped with a manual remote control, which can jog to control the up and down movement of the beam, easy to operate.
2.5 The controller can expand the test force measurement range by adding configuration load sensors.
2.6 Realize the automatic shift, zero adjustment, calibration and storage of physical zero adjustment, gain adjustment and test force measurement in the true sense, without any analog adjustment link, and the control circuit is highly integrated.
2.7 The electrical control circuit refers to the international standard and conforms to the national testing machine electrical standard. It has strong anti-interference ability, ensuring the stability of the controller and the accuracy of the experimental data.
2.8 It has a TMS network interface, which can carry out data transmission, storage, printing records and network transmission printing, and can be connected to the internal LAN or Internet network of the enterprise.
3. Description of main software features
The measurement and control software is used for microcomputer-controlled electronic
universal testing machines to conduct tests on various metals and non-metals (such as
wood-based panels), complete real-time measurement and display, real-time control and
data processing, result output and report printing in accordance with the corresponding
standards Features. The testing machine stiffness calibration function module and pre-test
analysis setting function module are embedded in the software to ensure that the test
