摘要
为确定滑板的磨损率及磨损机理,以耐磨低合金钢为研究对象,通过在往复式摩擦磨损试验机上进行试验的方法研究了摩擦过程中试样厚度变化规律,并观察接触表面形貌。在实验的基础上修正了Archard模拟模型,并进一步模拟分析了轮胎模具合模速度与磨损的关系。结果表明:耐磨合金钢的磨损以磨粒磨损为主,接触表面没有形成具有保护作用的润滑膜。提高轮胎模具的合模速度时,滑板磨损率变化平缓,但载荷越大,速度对磨损率影响越明显。
The wear-resistant alloy steel,material of wearing plate of tire mould was investigated in the reciprocating friction test.The variation of the sample’s thickness was studied during the test,and the contact surface was observed.According to the experimental data,the Archard wear model was modified to simulate and analyze the relationship between the clamping speeds and the wear loss.The results show that the abrasive wear is the main wear mechanism and there is no lubricating film appearing on the surface to reduce the wear rate.The clamping speed has little effect on wear rate.However,the greater the load is,the more obvious the effect of speed to wear rate is.
