【摘要】：针对叶片式连续回转电液伺服马达的内泄漏影响其低速性能的问题,基于流体力学理论,采用有限元数值分析方法研究连续回转马达内部流场分布情况。应用UG软件建立了马达内流场的三维模型,通过ICEM CFD进行网格划分,生成了高质量的O型网格。导入流体分析软件ANSYS CFX中,并设置合理的边界条件,经仿真计算得到了不同的压差及间隙下马达的内泄漏量分布规律。结果表明:高低压腔之间的压差越大,通过叶顶间隙的流体的流速也越大,并且内泄漏随着压差的增加而增加,为研究马达内泄漏对其低速性能的影响奠定了基础。
[Abstract]:In order to solve the problem that internal leakage of vane continuous rotary electro-hydraulic servo motor affects its low speed performance, the flow field distribution in continuous rotary motor is studied by finite element numerical analysis method based on the theory of fluid dynamics. The three-dimensional model of the internal flow field of the motor is established by using UG software, and the high quality O type mesh is generated by ICEM CFD. By introducing the fluid analysis software ANSYS CFX and setting reasonable boundary conditions, the internal leakage distribution law of the motor under different pressure difference and clearance is obtained by simulation. The results show that the greater the pressure difference between the high and low pressure cavities, the greater the flow velocity of the fluid passing through the vane clearance, and the more the internal leakage increases with the increase of the pressure difference, which lays a foundation for the study of the effect of the internal leakage on the low speed performance of the motor.
