1Fluid simulation of internal leakage for continuous rotary electro-hydraulic servo motor显示文摘The internal leakage has important influence on low speed performance of continuous rotary electro-hydraulic motors,and research on internal leakage is of important significance to improve the motor low speed performance. UG software is adopted to establish a flow field inside a motor,which ignores the gap between the blade and the blade groove,and a motor fluid model in different working conditions is established. Using ICEM-CFD to generate high-quality O-Net mesh for meeting the computing requirements,the flow field inside the motor is simulated using fluid simulation software CFX. Applying reasonable boundary conditions and then solving it,pressure field distribution and the variation rule of internal leakage with different pressure difference in the flow field are obtained when the clearance value of the motor key components is 0.01 mm. At the same time the motor's leakage experiment has also been done to verify the validity of the simulation results,which lays a foundation for the study of motor internal leakage effect on the low speed performance.王晓晶 Zhang Mengjian Man Guojia Cao Jian Xiu Liwei 2016High Technology Letters2016,22,4:1
