Explanation of three major features of electromagnetic resonance test machine

1. Electromagnetic resonant high-frequency fatigueTesting machineHost

1.1 The main machine frame adopts a door-type structure and is driven by a double screw, with high stiffness and large test space, and can ensure coaxiality well. Ensure the accuracy and stability of the test data. The lower seat has a ladder-shaped groove, making the sample clamping very convenient.

1.2 The host uses a mechanical model with multiple degrees of freedom for optimization design, so that the dynamic force error is much smaller than that of similar products, and its volatility index is higher than that of similar products (static test force accuracy ±0.5%, and static and dynamic test force fluctuations are as high as ±0.5%).

1.3 Due to the unique features of host model analysis and design, our company's high-frequency machines generally do not require dynamic test force compensation within the entire frequency range.

1.4 The AC servo motor and servo drive system are made of Japanese Panasonic products, with a wide speed regulation range and high reliability.

2. Electromagnetic resonance high frequencyFatigue testing machineControl system

2.1 The control system adopts a digital closed-loop control system, intelligent digital frequency selection, which can effectively suppress interference from non-resonant frequency and automatically track frequency, phase, etc., so that the control system can always work at the main resonant point, have small waveform distortion, stable work, easy vibration, and will not stop vibration with the changes in the performance of the sample or component itself.

2.2 It has functions such as conventional fatigue test (symmetric or asymmetric), block spectrum fatigue test, modulation and control fatigue test.

2.3 Automatic zeroing and automatic calibration of the load amplifier.

2.4 It has protection functions such as overload, overstroke, overvoltage, overcurrent, and overheating; it can set up upper and lower limits of load protection at will; it has automatic shutdown of accidents and automatic shutdown of sample breaks; it can automatically record test data to ensure the effectiveness of the test.

3. Electromagnetic resonant high-frequency fatigue testing machine computer and software system

3.1 The computer direct and control system are closely coordinated to manage and control the test system. On the computer, it adopts the form of a virtual panel and is operated in a button form. Control the entire test.

3.2 It has the function of equal-rate test of fatigue crack propagation, and can also complete isostress fatigue tests in fatigue crack propagation.

3.3 Support network function, which can be monitored (or authorized monitoring) in offices, homes, etc. During the test, the protection function can be complete, and the stability and reliability are higher than other similar products.
