| 摘 要： | 针对风力发电机齿轮箱的高可靠性要求,提出了一种加速疲劳试验技术方法来验证齿轮箱的疲劳可靠性.根据齿轮箱的设计载荷谱,推导了其主要零件在寿命周期内的等效栽荷和应力循环次数;应用Miner线性累积疲劳损伤理论,计算了齿轮和轴承在设计寿命周期内的疲劳损伤度;采用线性强化载荷谱的方法建立了风电齿轮箱加速疲劳试验载荷谱,结果在大约800 h左右就验证了齿轮箱的疲劳可靠性.

| Abstract: | In order to satisfy the high reliability requirements of wind turbines gearbox,a method of accelerated fatigue test is proposed to verify the fatigue reliability of the gearbox.According to the design load spectrum, the equivalent load and the number of stress cycles of parts in gearbox are deduced.Based on Miner linear cumulative damage theory,the fatigue degree of the gears and bearings are calculated.A linear accelerated load spectrum with the equivalent fatigue ratio of design load spectrum is provided ... |
