| 在密炼机密封端面设置圆-椭圆垂直复合微孔织构（以下简称复合织构），建立复合织构化端面密封模型，基于流体动压润滑理论研究考虑粗糙效应时密炼机复合织构化端面密封装置的摩擦性能和密封性能。结果表明：不同综合粗糙度参数下复合织构化端面在织构深度（hp）为4～6 μm时，端面密封装置的摩擦性能较好，密封性能较差；不同粗糙度纹理方向参数下复合织构化端面在hp为5～7 μm时，端面密封装置的摩擦性能较好，密封性能较差；随着复合织构化端面织构面积率的增大，端面密封装置的摩擦性能变好，密封性能变差。 |
| 英文摘要: |
| The circle-ellipse vertical composite microporous texture （hereinafter referred to as composite texture）on the sealing end-face of the internal mixer was set up，and a composite textured end-face sealing model was established.Based on fluid dynamic pressure lubrication theory，the friction performance and sealing performance of the composite textured end-face sealing device of the internal mixer were investigated considering the roughness effect.The results indicated that，under different comprehensive roughness parameters，when the texture depth（hp） of the composite textured end-face was 4～6 μm，the end-face sealing device exhibited good friction performance but poor sealing performance.Under different roughness texture direction parameters，when the hp of the composite textured end-face was 5～7 μm，the end-face sealing device showed too good friction performance but poor sealing performance.With the increase of the texture area ratio of the composite textured end-face，the friction performance of the end-face sealing device was improved，while its sealing performance was reduced. |
