3 Test principle

Reciprocating Flexing fatigue test specimen is dipped cord bend radius greater than the minimum radius of curvature (see Appendix A), at certain load conditions Next, the two freely rotatable guide roller A, B at the same time as the upper and lower reciprocating motion, so that the cord was measured by the bending fatigue resistance cord reciprocating fatigue after The method of labor performance. Cord fatigue resistance can be broken when each cord Flexing fatigue reciprocating number of times that can also be used subject to certain The number of reciprocating Flexing fatigue cord breaking strength retention to represent.

4 instruments and equipment

4.1 Reciprocating Flexing fatigue tester Reciprocating flexing fatigue tester consists of freely rotatable guide roller, weight (including under the holder), the composition of the transmission and recording section, such as Shown in Figure 1, it should have the following means. a) You can adjust the frequency of reciprocation; b) tension adjustment means may be; c) You can set the number of reciprocating bending fatigue means; d) reciprocating bending frequency counting means. ......
