在润滑数值模型的基础上

通过计算得出压室和冲头在不同间隙下的载荷

研究了在不同载荷和润滑剂下的摩擦特性。结果表明

在定载荷下

冲头润滑油具有较好的润滑性能

对磨副间的摩擦因数为0.16

且变化幅度较小。在美孚齿轮油作用下

随着载荷的增大

由于摩擦副间形成了良好的润滑油膜

摩擦因数从0.43降到0.07

而且试验值和数值模型值间的误差保持在10%之内

证明了试验方案的合理性。

Based on the lubrication numerical model

the load between the chamber and punch in the different gap was calculated

and then the friction characteristics were investigated at different loads and lubricants.The results show that

at the given load

the punch lubricant exhibits a satisfied lubricating properties

and the frictional coefficient between the friction pair is 0.16 with the very low change range.By using Mobil gear oil

with the load increases

the friction coefficient is changed from 0.43to0.07 due to the good lubricant films formed between the friction pair

and error between the experimental and numerical model is within 10%

verifying the experimental rationality.
