fatigue lifetime meaning in Chinese
疲劳寿命
Examples
- Prediction for intermediate and high cycle fatigue lifetime of notched metallic plates
含缺口金属构件的中高周疲劳寿命预测 - The application of fatigue failure criteria to low - cycle fatigue lifetime prediction of titanium alloy bt
9低周疲劳寿命估算中的应用 - In chapter 3 , it introduces the fatigue failure of the axle . we analyze fatigue lifetime of the axle by the miner theory
第三章、驱动桥疲劳失效分析及其试验技术研究本章着重对驱动桥的疲劳性能进行了分析。 - And the finite element method ( fem ) was used to simulate the stress and deformation of the outer casing and the bearing chock . on the basis of the experiments and fem analysis , the strength and fatigue lifetime , the interaction of creep and fatigue lifetime , the creep lifetime of outer casing and bearing chock have been analyzed , at the end of trail , sem analyses of failure section has been conducted
同时对航空发动机燃气涡轮外机匣和轴承座进行了有限元模拟计算，得到外机匣和轴承座的焊接处的强度和变形情况的模拟结果。根据试验数据和有限元的计算结果，对发动机燃烧室外机匣和轴承座两种结构(包含焊缝)进行静强度分析、疲劳寿命分析、蠕变寿命分析、蠕变疲劳交互作用寿命分析以及断口的金相分析。 - And finally , sem has been used to characterize the fracture . the results indicate that the relationship between the fatigue lifetime and cyclic plastic strain range obeys coffm - manson relation , and the relation between the hysteresis energy ( wn ) and the plastic strain range ( p ) can be described by a power - law : wh = h pw
但在室温下， r向及t向试样具有相同的循环特性，均表现为随应变幅的不同而不同，当应变幅高于0 . 8时，呈现出先循环硬化而后循环软化直至最后断裂的现象。
