密炼机啮合转子的三维流场模拟

3D Fluid Field FEA on Meshing Rotors of Mixer

采用ADINA有限元分析软件对啮合转子所形成的三维流场进行模拟分析,得到转子6个啮合相位角的速度场分布。分析发现,啮合转子混炼区在两转子啮合区域,并且啮合区域为高压力区,高压力点在短棱附近,为设计时校核转子强度提供了校核危险点,并为转子设计提供了可靠的理论依据和技术参数。

Meshing rotor＇s three-dimensional flow field was simulated to get meshing rotor velocity field with six phase angles using the FEA software ADINA.The results showed that the mixing zone area of meshing rotor was maily occurred in the two rotor engagement,engagement area was the high-pressure zone,and the high-pressure points were around the short edge.The study provided the key checking points of rotor strength,and a reliable theoretical basis and technical parameters for the rotor design.
