二層止め輪の疲労試験

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 製品 これは主に、疲労寿命の検証や設計部品の信頼性を評価するためのものである。 製品 or designed parts. One is the test to determine the fatigue limit or s–n curve of double-layer snap ring 材料. The purpose of this kind of test is mainly to provide data for デザイン; 1 つは、疲労強度や寿命に対する外部要因の影響を判断することです。この種のほとんどは比較テストであり、主に製品を改善するためのデータと根拠を提供します。 品質 と デザイン.

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.
