1 适用范围 本标准用于金属多层轴承材料普通平带材料试件的疲劳强度应力测定。并可研究带材上液体压力和均匀温度的影响。 2 参考标准 ISO/R373 金属实验的一般原理 DIN50100 材料试验─疲劳试验（Wohler实验）的定义、符号、实施及判定 ISO3548 滑动轴承 薄壁轴瓦尺寸、公差及检验方法 ISO4378/1 滑动轴承 术语、定义及分类。第一部分:设计、轴承材料及其性能 3 试件 试件为具有矩形截面的平弯曲带。为避免试件在试验中在夹紧处断裂,锐边要用磨削的方法仔细修正,并减小试验截面的宽度。见图1。
1 Scope This standard is used for multi-layer metal bearing plain flat material specimens fatigue strength stress measurement. The effect of liquid pressure and uniform temperature on the strip can be studied. 2 Reference Standard ISO / R373 General Principles of Metallic Testing DIN50100 Material Testing-Definition, Symbol, Implementation and Decision of Fatigue Test (Wohler Test) ISO3548 Plain Bearing Thin-walled Bushings Dimensions, Tolerances and Test Methods ISO4378 / 1 Plain Bearing Terms, Definitions and classification. The first part: design, bearing materials and their performance 3 specimen specimen is a rectangular section with a curved strip. To avoid breaking the specimen at the clamp during the test, the sharp edges should be carefully modified by grinding and the width of the test section should be reduced. see picture 1.
