疲劳试验数据
疲劳数据
Examples
- Strain - life fatigue data exchange file format
应变周期疲劳数据交换文件格式 - When strain amplitude is lager than 0 . 5 % , it is better to employ the fatigue data of 3 / 10 life section ; as to strain amplitude lower than 0
5时，采用3 10寿命阶段的疲劳特性参数预测结果较符合实验值；但当应变幅小于0 - Statistic analysis on fatigue load effect and equivalent stress range of steel crane structures in service is carried out . the stress range distribution in whole life is deduced by the spot measurement little sample stress - time process . meanwhile the statistic analysis on the fatigue resistance process is conducted , according to fatigue data of all kinds of structural joints in domestic and overseas , which is foundation with , establish the fatigue reliability model
2 、在大量调查的基础上，对吊车梁所承受的疲劳荷载效应与等效等幅应力进行了统计分析，同时根据国内外有关各构造细节的疲劳资料对疲劳抗力参数进行了统计分析，为建立疲劳动态可靠性分析模式奠定基础。 - For rotor steel ( 30crlmolv steel ) , the tests of low - cycle fatigue property are done under different temperatures . the fatigue life under different temperatures is researched to make up for the defects of the testing for foreign similar materials . when pull - stretch data is attempted to evaluate low - cycle fatigue data , the result shows that four - point associated method in middle - low life zone is done well under room temperature , but there are large errors of four - point associated method and general - slope method under other temperatures
在本文中，通过与国外同类材料的性能进行比较，国产材料与国外材料共有的材料特征基本相同；对转子钢( 30crlmolv钢)进行了不同温度下的低周疲劳性能实验，研究其在不同温度下疲劳寿命，以弥补国外对同类钢材测试的不足；采用拉伸数据预测低周疲劳寿命时发现，室温条件下用四点关联法在中低寿命区预测较好，在高温条件下四点关联法和通用斜率法都有较大误差，需要进行改进。
