Introduction to the load of high-frequency fatigue tester

High-frequency fatigue in production and sales of Jinan Hengsi Shanda Instrument Co., Ltd.Testing machineThere are many technical parameters, and the operating standards are relatively complex. The manufacturer uses many years of experience in production testing machines to provide consumers with a comprehensive introduction and a careful understanding.

High-frequency fatigue testing machine (recommended: electronic tension testing machine):

Technical parameters test force: 250kN /500KN /1000KN

Dynamic performance: When the operating frequency is 300Hz:

- Fastener fatigue test with an average load of zero and an amplitude of 75kN can be completed.

- Fastener fatigue test with an amplitude of 75kN can be completed when the mean load is 100kN.

Static load: 150kN.

Dynamic load: ±125 kN. (Peak)

Coaxiality of upper and lower chucks: ≤2%.

Load measurement accuracy: ±0.5%.

Load fluctuation: dynamic load ≤±0.5% F.S.; static load ≤±0.5% F.S.

Main features equipment (recommended: experimental equipment) uses and basic requirements:

High frequency fatigueTesting machineIt is mainly used to determine the fatigue properties of various metal materials at high frequencies, S/N curve measurement, crack propagation, threshold value and fracture toughness and other mechanical properties.

The equipment must adopt advanced design ideas in the same industry internationally. Mature manufacturing technology must have excellent quality and reliability, good operation, convenient maintenance and safety, and the technology used must comply with the corresponding international standards and Chinese national standards.

The equipment will not endanger personal health during use (providing relevant verification or testing evidence).

The high-frequency fatigue testing system can work continuously for more than 120 hours under load, and overload of 120% will not cause damage to the test machine.

The overall energy consumption of the equipment must meet environmental protection requirements, and the total power consumption generally does not exceed 8kWA.

Equipment design and manufacturing should comply with ISO international standards.

The equipment adopts a fully digital servo control system, and the working frequency meets 30~300Hz; frequency resolution: not less than 0.1Hz.
