双层弹性挡圈的疲劳试验有哪些

How should the Double snap ring 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 材料, 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.

双层卡簧疲劳试验的目的大致可分为三类：一是测试 产品 or designed parts, which is mainly to verify the fatigue life and evaluate the reliability of 产品 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 设计;一是确定外部因素对疲劳强度或寿命的影响。这种多为对比试验，主要为改进产品提供数据和依据 质量 和 设计. The above is the introduction of fatigue test of double-layer circlip.
