Driving Axle Housing Accelerated Fatigue Bench Test Based on FEA 基于有限元分析的车辆驱动桥壳台架加速疲劳试验
Analysis of accelerated fatigue test technology for wind turbines gearbox 风力发电机齿轮箱加速疲劳试验技术分析
Failure probability was used as a damage parameter. On the basis of an accelerated pre-corrosion and fatigue test under an environmental corrosion equivalent relation, the calendar life could be estimated by the failure probability according to the distribution form and the probability density functions of fatigue life. 选取破坏率为损伤参量,在环境腐蚀当量关系加速预腐蚀疲劳试验的基础上,通过疲劳寿命分布形式和概率密度函数求出破坏率来估算预腐蚀环境下的日历寿命。
To clarify the subsurface crack initiation mechanism in gigacycle fatigue, several alloy steels were tested at very high numbers of cycles through ultrasonic accelerated fatigue test at 20 kHz. 通过20kHz压电超声加速疲劳试验机对多种金属材料进行测试,实验地证明了超高周疲劳裂纹往往从试件内部萌生的机制。
