Planetary Gear Trains (PGTs) are widely used in industry and many other applications. In some of the applications, the loads to which the PGTs are subjected are random/stochastic. Two representative scenarios where PGTs are used as a transmission unit, and subjected to random loads include wind turbines in wind energy industry and directional drilling in oil and gas industry. Fatigue caused by the vibration in these systems is a outstanding issue in the industries, and has huge economical consequence. However, the random nature of the vibration stresses largely hinders accurate fatigue prediction and proper fatigue management.

行星齿轮火车（PGT）在行业和许多其他应用中广泛使用。在某些应用中，对PGT的负载是随机/随机的。 PGT用作传输单元并承受随机负载的两种代表性场景包括风能行业中的风力涡轮机和石油和天然气行业的定向钻探。这些系统振动引起的疲劳是行业的一个重大问题，并且具有巨大的经济后果。但是，振动的随机性质在很大程度上阻碍了准确的疲劳预测和适当的疲劳管理。
