基于ADINA对六棱同步转子混炼流场的有限元分析

FEA of Flow Fluid for Six-Wing Synchronous Based on ADINA

专用于短纤维补强橡胶复合材料混炼的新型六棱同步转子的构型特殊,故混炼过程中胶料的流动状态也十分复杂。利用有限元分析软件ADINA对短纤维补强橡胶复合材料混炼过程中六棱同步转子的流场,进行了模拟分析,内容主要包括压力场、黏度场,剪切应力场和速度场。分析了模拟流场的流动特性,以进一步判断和分析胶料的混炼状态。

Short fiber-rubber composite material has special mixing requirements. So, the new type six-wing synchronous rotors which have been designed for the mixing of short fiber-rubber composite material have special structure, and considering the characteristic of the short fiber-rubber composite material, the flow situation of the mixed rubber is very complex. However, the flow field of the sixwing synchronous varying clearance rotors can be analyzed by ADINA. The flow situation and mixing situation of the mixed rubber can be analyzed and judged by the FEA results such as the pressure field, viscosity field, shearing force field and velocity field.
