| 摘 要： | 以智能四驱车辆分动器的输出轴齿轮及对其润滑的流体润滑油为对象,基于ADINA软件建立三维齿轮结构和流体模型,并对齿轮在转动过程中润滑油流体的耦合进行了分析。以FSI计算结果为基础,应用分离法,分析了齿轮在转动过程中润滑油流体的流动趋势及位移、速度变化趋势。结果表明:齿轮在转动过程中流体会形成一定的湍流,且齿附近的位移及速度有一定的变化。

| Abstract: | The 3D model of the gear structure for Power transfer unit(PTU) of the intelligent 4WD vehicle and lubrication gear fluid was established by ADINA software.The oil fluid coupling in the gear rotation process was analyzed in ADINA.The fluid flow trend,oil displacement and velocity changing trend in the process of gear rotation were analyzed by using partition method based on the FSI calculation results.The results show that the oil fluid in the gear rotation process can form certain turbulence,and the displacement and speed nearby the tooth have a certain change. |
