Abstract

The theory of lubrication of plastically deformed surfaces (plasto-hydrodynamics or PHD) was derived in the 60s using the advances in elasto-hydrodynamics (EHD). The transposition is described together with some applications to metal forming processes. PHD was later extended to the mixed regime, so important in metal forming. These models are surveyed. Finally, it is suggested that mixed PHD models could considerably benefit from newer algorithms and numerical techniques used in EHD and more recently in mixed-EHD.

塑性流体动力润滑——润滑理论在金属成形过程中的应用
塑性变形表面的润滑理论(塑性流体力学或PHD)是在60年代根据弹性流体力学(EHD)的进展而发展起来的。介绍了换位法及其在金属成形工艺中的一些应用。PHD后来扩展到混合状态,在金属成形中非常重要。对这些模型进行了调查。最后,混合博士模型可以从EHD和混合EHD中使用的较新的算法和数值技术中获益。
