Electromagnetic high-frequency vibration test bench, first-rate brand design, electromagnetic high-frequency vibration test bench is required to use every small piece is carefully made and then assembled. Below, the Haida technicians will introduce how the electromagnetic high-frequency vibration test stand is made!
First, use:
1, widely used to test the resistance of various metal materials against fatigue fracture, test KIG value, S - N curve, etc.; optional different fixture or environmental experimental device
2. To test the fatigue life of various materials and components (such as plates, gears, crankshafts, bolts, chains, connecting rods, compact tension, etc.) to complete symmetric fatigue tests and asymmetric fatigue tests.
Second, characteristics:
1. The main frame of the main engine adopts a gate structure, double screw drive, high rigidity, large test space, and good coaxiality. Guarantee the accuracy and stability of test data.
2. The lower pedestal has a ladder slot, and the sample is clamped very conveniently. The host uses a multi-degrees of freedom mechanical model to optimize the design, so that the dynamic force error is much smaller than similar products, and its volatility index is higher than similar products.
3. The uniqueness of the host model analysis and design, so that the company's high-frequency machine generally does not require dynamic test force compensation over the entire frequency range.
4. The control system adopts a digital closed-loop control system and intelligent digital frequency selection, which can effectively suppress the non-resonant frequency interference, and automatically track the frequency and phase, so that the control system can always work at the host resonance point, and the waveform distortion is small. , The work is stable, easy to start, and does not stop with the changes in the performance of the sample or component itself.
5, with a conventional fatigue test (symmetric or asymmetric), block spectrum fatigue test, modulation control fatigue test and other functions.
6, with overload, over-travel, over-voltage, over-current, overheating and other protection functions; can be arbitrarily set load protection upper and lower limits;
7. With automatic shutdown of the accident and automatic shutdown of the sample fracture; automatic recording of test data to ensure the validity of the test.
The above is the characteristics of the use of electromagnetic vibration testing machine, Haida Instrument specializing in the production of electromagnetic vibration testing machine.
