flexural fatigue test meaning in Chinese
挠曲疲劳试验
Examples
- Tests relating to pavements . determination of fatigue resistance on material bound with hydraulic binders . part 1 : flexural fatigue test with constant stress
路面试验.水硬性粘结剂材料疲劳性能测定.第1部分:恒定应力挠性疲劳试验 - By analyzing the indoor flexural fatigue tests of small beams , the paper concludes that the fatigue life of lean concrete follows the two - parameter weibull distribution , and establishes two types of fatigue equation under different stress level and equivalent stress level
通过分析室内小梁弯拉疲劳试验结果，得出贫混凝土的疲劳寿命服从双参数威布尔分布，据此建立了不同应力水平和等效应力水平下两种形式的疲劳方程。 - Abstract : based on the analysis of the main failures discovered in pavement on steel deck plate and the demanding service condition of the pavement on steel deck , high - temperature rutting test , low - temperature bending test and controlled stress flexural fatigue test are used to study the performance of asphalt mixtures modified by epoxy resin including high - temperature stability , low - temperature cracking - resistance , and fatigue cracking - resistance , which are served to evaluate the modification effect of epoxy resin of different contents . with the addition of epoxy resin , all the three performances are improved greatly . however , when the amount of epoxy resin added is over a certain value , the modification effect will be stable with no extra benefit detected . finally , in terms of the properties of the three respects , 20 ? , 30 ? , 30 ? are given separately as the proposal adding contents
文摘:在分析钢桥面铺装层主要病害和特殊工作环境的前提下,分别采用高温车辙试验、低温小梁弯曲试验和控制应力小梁弯拉疲劳试验,研究了不同环氧树脂掺量下的环氧树脂改性沥青混合料的高温稳定性、低温抗裂性和抗疲劳性能.试验结果表明:环氧树脂对这3个方面都有很大的改进效果,但改性效果和树脂的添加量并不是一个无限递增的关系,当添加量超过一定数值以后,改性的效果将趋于平稳.最后就高温、低温、疲劳3个方面分别提出环氧树脂添加量为20 ? , 30 ? , 30 ?的建议值 - Based on the analysis of the main failures discovered in pavement on steel deck plate and the demanding service condition of the pavement on steel deck , high - temperature rutting test , low - temperature bending test and controlled stress flexural fatigue test are used to study the performance of asphalt mixtures modified by epoxy resin including high - temperature stability , low - temperature cracking - resistance , and fatigue cracking - resistance , which are served to evaluate the modification effect of epoxy resin of different contents . with the addition of epoxy resin , all the three performances are improved greatly . however , when the amount of epoxy resin added is over a certain value , the modification effect will be stable with no extra benefit detected . finally , in terms of the properties of the three respects , 20 ? , 30 ? , 30 ? are given separately as the proposal adding contents
