| Abstract: | The paper obtains fatigue life data of joint points for angle truss structure of tower crane through the test of fatigue life. According to the feature of this kind of small sample volume test. The writer uses a statistic method with high efficiency and gets P al S N curve of that joint POint. It lays the foundation for evaluating fatigue life further. |
