The high-frequency fatigue testing machine is mainly used for fatigue performance testing or fatigue limit testing of various valve springs, clutch springs, injector pressure regulating springs, and other springs. It is suitable for online testing by manufacturers of valve springs and clutch springs, as well as for the production of engine, automotive, and motorcycle parts industries.
The structural characteristics of high-frequency fatigue testing machine:
1. Mainly used for dynamic and static testing and fatigue resistance testing of organisms, elastomers, small specimens, etc.
2. Double column frame structure, linear actuator mounted, equipped with T-shaped worktable, convenient for testing different specimens. The appearance of the testing machine has been specially treated to improve its wear resistance and corrosion resistance, and the appearance is aesthetically pleasing.
3. Linear motor drive has a compact structure, small volume, no need for lubricating oil and hydraulic oil, clean environment, no noise, and maintenance free.
4. It has the characteristics of self checking, self zeroing, automatic reset, and control.
5. The experimental frequency range is wide, enabling wideband testing. The testing machine can conduct various tests under sine wave, triangular wave, square wave, trapezoidal wave, oblique wave, and user-defined waveform. Real time display, playback, amplification, analysis, storage, and output functions of experimental data.
The high-frequency fatigue testing machine is used to determine the fatigue characteristics, fatigue life, and fatigue crack pre testing of metal and alloy materials (plates, bars) under tension, compression, or alternating tension compression loads.
1. It has functions such as conventional fatigue testing, block spectrum (programmable) fatigue testing, etc; Real time display of dynamic load waveform function;
2. It has complete protection functions and the testing process can be unmanned;
3. Equipped with remote manual operation function for easy remote operation and control;
4. There are two control methods: conventional fatigue testing (axial tension compression symmetric, asymmetric, and unidirectional pulsation testing, which can cross zero) can achieve closed-loop control, automatic constant load, and constant amplitude for more than 100 hours; Program controlled loading test;
5. It has complete protection functions. In addition to overload protection and overcurrent protection, it also has arbitrary settings for alternating load upper and lower limit protection, average load upper and lower limit protection, frequency protection, and test fracture protection.
