| 中文摘要: |
| 通过粘弹性流体软件Polyflow对胶料在有无超声波两种试验条件下的混炼过程进行模拟，研究超声波对胶料的分散、分布及流动的影响。结果表明，加载超声波可缩短流场出现最高压力和浓度的时间，加快粒子的分散速度，增强胶料在转子螺棱顶部与混炼室内壁间隙处的剪切作用，减小转子凸棱处的粘度，促进橡胶和配合剂在两个腔体内的分布混合，更快地完成分散和混合过程，明显提高混炼效率和胶料质量。 |
| 英文摘要: |
| By professional viscoelastic fluid software（Polyflow），the mixing process of compound with or without ultrasonic-aided condition was simulated to study the effect of ultrasonic on the dispersion，distribution and flow of the compound.The results showed that，under ultrasonic-aided condition，the time for the pressure and concentration of the flow field to reach their peaks was shortened，the particle dispersion speed was accelerated，shearing action of the compound in the gap between the tip of the rotor screw flight and chamber body was enhanced，and the viscosity at screw flight was reduced，which could facilitate the distributed mixing of rubber and additives in two cavities，and accomplishe the dispersion and mixing process faster to improve the efficiency of mixing and compound quality significantly. |
