Essai de fatigue du circlip double couche

How to conduct the fatigue test of double-layer snap ring? Now let’s have a look! The purpose of double-layer snap ring fatigue test can be roughly pided into three categories: one is to test des produits ou des pièces conçues, ce qui permet principalement de vérifier la durée de vie en fatigue et d'évaluer la fiabilité des pièces. des produits or designed parts. One is the test to determine the fatigue limit or s–n curve of double-layer snap ring matériel. The purpose of this kind of test is mainly to provide data for conception; l'une consiste à déterminer l'influence de facteurs externes sur la résistance à la fatigue ou la durée de vie. Ce type est principalement des tests comparatifs, qui fournissent principalement des données et une base pour améliorer le produit qualité et conception.

For the test of double-layer snap ring material, it is not easy to make a middle thin test bar for fatigue test because the surface state, drawing degree and overall dimension of the raw material are different from those of ordinary steel. If the double-layer snap ring material is clamped directly on the testing machine, because the clamping part will have additional stress, this part will be destroyed first, and it cannot reflect the real fatigue strength of the material. Therefore, the fatigue strength test of the double-layer snap ring material is generally carried out with the rolled double-layer snap ring. Even so, due to the influence of many factors, the test value is also very discrete, and the allowable stress is often difficult to judge. The above is about the fatigue test of double-layer snap ring.
