| 摘 要： | 基于Evans-Johnson流变模型和理想粘塑性流变模型对粘塑性流体弹流润滑进行了数值求解。结果表明:基于两种模型所得到的油膜压力分布没有本质的区别,但油膜厚度有很大的不同,其中由前者所得的中心膜厚比由后者所得的中心膜厚低。

| Abstract: | Numerical calculation results were obtained based on Evans-Johnson and viscoplastic fluid model.Results show that there is no difference in pressure distribution based on the two above model.But the central oil film thickness calculated by Evans-Johnson model is thinner than that calculated by viscoplastic fluid model.This kind of difference is mainly brought about by parameter. |
