摘要建立了启动过程超高分子量聚乙烯(UHMWPE)轴承的弹流润滑模型。综合考虑加速过程伴随振动与冲击载荷耦合时变效应，数值模拟了UHMWPE轴承不同工况下启动时的润滑情况，以期为实际工况中UHMWPE轴承的安全运转提供参考。结果表明：冲击对压力的影响较大，而振动对膜厚的影响较大。轴法向振动与海浪冲击同周期下，当两者变化一致时，将产生叠加的协同作用，反之则相互削弱。其中负正弦振动对压力和膜厚的影响更为明显。随着加速度的增大，压力随之降低，膜厚随之增大，膜厚增幅变大，振动对压力和膜厚的影响变小。

Abstract：An elastohydrodynamic lubrication model of the ultra-high molecular weight polyethylene (UHMWPE) bearing during the start-up was established.The acceleration with vibration and shock coupled time-dependent effect was comprehensively considered.The lubrication condition of the UHMWPE bearing under different working conditions was numerically simulated for reference to ensure safe operation.The results show that the effect of impact on pressure is greater, and the vibration has a greater influence on film thickness.When the normal vibration of the shaft and the impact of the waves are in the same period and both changes are the same, there will be a synergetic effect of superposition, and vice versa.The effect of negative sinusoidal vibration on pressure and film thickness is even more pronounced.As the acceleration increases, the pressure decreases, the film thickness increases, and the effect of vibration on the pressure and film thickness becomes smaller.

Key words： ultra-hight molecular weight polyethylene(UHMWPE) bearing start-up shaft vibration wave shock coupled time-dependent effect elastohydrodynamic lubrication
