Electromagnetic resonance loading high-frequency testing machine is a device used to apply a load to a specimen and complete mechanical performance testing. It is possible to apply high-frequency alternating loads and inertial loads to the specimen in a resonant manner within the allowable range of machine load, space, and environment; Apply static load through elastic force. The loading methods can be various, such as tension, compression, bending, shearing, twisting, etc. The specimen can be any component presented in solid form, regardless of material or shape. It can be a special environment such as high temperature, high humidity, salt spray, etc. The machine has the functions of three traditional machines: electromagnetic resonance loading high-frequency testing machine, electronic universal testing machine, and vibration table, achieving multiple uses for one machine. The purpose of the machine is not particularly limited in terms of the industry, and it is suitable for any necessary loading test to obtain mechanical performance indicators of the specimen, including fatigue performance, strength, stiffness, deformation and other performance indicators.
1) Energy saving
Working in electromagnetic resonance loading mode, theoretically the machine requires almost no external energy consumption. Compared with the electro-hydraulic servo method that applies the same load, it can save more than 98% of electrical energy. The experiment requires almost no electricity consumption. It is the most energy-efficient working machine.
2) High work efficiency
It usually operates at high frequencies, completing 10 ^ 7 alternating loads. If the operating frequency is 200Hz, it takes 13.9 hours. This device has a design frequency that is higher than the operating frequency of traditional machines, from mechanical to electrical control. The maximum frequency allowed is 1.5 times the standard specified, reaching 450Hz. The average work efficiency has also increased by about 50%. As mentioned above, with 10 ^ 7 loads and a working frequency of 350Hz, the test took 7.9 hours.
3) Large amplitude
Due to the limitation of electromagnetic excitation principle, the amplitude is generally small. There is no specified amplitude in the standard for high-frequency fatigue testing machines. But in many experiments, the amplitude is not too small. The maximum amplitude of the test piece designed for this device is 6mm, and the factory setting is 3mm. It can meet the amplitude requirements of various loading forms, materials, and shapes.
4) The force sensor can be placed on top
In order to meet the requirements for specimen installation in the experiment, the force measurement sensor of this equipment can be installed on top as needed, freeing up sufficient and flexible installation space for special specimens. The force measurement after placement is equipped with an acceleration sensor to offset the force measurement error caused by inertial force and ensure the accuracy of the measured force value.
5) Multi functional
This device combines the functions of three traditional devices: high-frequency fatigue, electronic universal, and electromagnetic excitation. It can switch working modes freely through an extremely simple method. Each working mode complies with professional design standards and includes most of the dynamic and static mechanical performance tests of materials and components, making it a truly universal testing machine.
