A new type of friction and wear tester with high frequency alternative load

A new type of friction and wear tester with high frequency alternative load

——Say goodbye to static testing and embrace the real working conditions

    Have we long neglected a key factor in the field of material friction and wear research? Traditional wear tests are always carried out under constant load, but real world components - from gears to bearings to engine pins - are constantly subjected to violent fluctuations of the load. This gap between "laboratory data" and "actual performance" has always been a central pain for engineers and researchers.

Therefore, we have successfully developed a high frequency alternative load friction and wear fatigue testing machine, aimed at uncovering the truth of material failure under dynamic load, and pushing the test of friction and wear to a new height.

1、 Why are constant load tests no longer sufficient?

The traditional constant load test is the basic method of material screening by tribometer, but its limitations are obvious:

1. Failure to simulate fatigue effects: Materials also fail due to "fatigue" at alternate stresses well below their strength limits. Constant load testing does not capture this key mechanism.

2. Great difference in the micro world: the material surface is rough, and the actual stress at the micro contact point is huge. Alternate loads cause repeated stress cycles on these micro projections, which can easily lead to micro cracks and spalling, while constant loads can not reproduce this process.

3. Disjoint with the actual working condition: the load in the real working condition is dynamic. Component life prediction from constant load data alone is often biased, as is the case when testing a ship's wave resistance on a calm lake.

2、 Our solution: reproduce true stress fluctuations

This alternate load friction and wear tester perfectly addresses these issues. It innovatively integrates a high-performance dynamic loading system on top of standard friction and wear testing functions:

1. Core advantage: High frequency and dynamic alternative load can be applied to the friction pair.

2. Key indicators: Maximum AC frequency can reach 10Hz, which can accurately simulate load fluctuation in most practical projects.

3. Flexible configuration: support a variety of wave forms such as sinewave and square wave, and can stack dynamic loads on the constant load base to meet the simulation requirements of a variety of complex working conditions.

3、 Core Value for You

This device is not only an instrument, but also a key partner for you to understand the nature of material failure and improve product reliability.

1. For researchers: revealing the "wear fatigue" coupling mechanism, publishing higher level academic results, promoting the development of the theory of friction.

2. For the material engineer: more accurately evaluate the wear resistance and life of the coating and composite materials under the simulated working conditions, and optimize the material formula and process.

3. For product designer: obtain the key data based on fatigue failure, provide a solid basis for the design of high reliability parts, shorten the R&D cycle, and reduce market risk.

4、 Closing remarks

The study of friction and wear cannot be stopped in the "static" state, but must move to the "dynamic" state. We have launched the high frequency alternative load friction and wear testing machine, is to fill this gap, so that laboratory tests unlimited access to the real world.

We invite all experts, scholars and engineers in the field of material science and mechanical engineering to experience this innovation platform, jointly explore the deeper secrets of friction and wear, and empower your scientific research and product development.

Welcome to inquire, looking forward to cooperation!
