Double snap ring how should the fatigue test be carried out? This test should be carried out after the production of double-layer circlip. Let’s learn about it together! For the test of double-layer circlip material, because the surface state, drawing degree and overall dimension of raw materials are different from those of ordinary steel, it is not easy to make a middle thin test bar for fatigue test. If spring material is used.
The purpose of double-layer circlip fatigue test can be roughly pided into three categories: one is to test products or designed parts, which is mainly to verify the fatigue life and evaluate the reliability of products or designed parts. See Chapter 5 and GB / t7684-96 for the specifications of such tests of springs. One is the test to determine the fatigue limit or S-N curve of spring material. The purpose of this kind of test is mainly to provide data for design; One is to determine the influence of external factors on fatigue strength or life. This kind is mostly comparative tests, which mainly provides data and basis for improving product quality and design. The above is the introduction of fatigue test of double-layer circlip.
