考虑不同载荷顺序下应力损伤模糊性的Miner法则
MINER RULE CONSIDERING FUZZINESS OF STRESS DAMAGE UNDER DIFFERENT LOAD SEQUENCES
摘要
Abstract
Since the traditional Miner rule ignores the influence of the load sequence on the fatigue life,the fuzzy rules are used to analyze the fuzziness of the fatigue damage caused by the stress nearby the fatigue limit under different load sequences.The improved fuzzy Miner rule can reflect the influence of the load sequence on the fatigue life.Results of the example show that the prediction error can be reduced from 61.6% to 21.7%.关键词
