摘要

研究了液浮转子式陀螺仪转子在高速转动时其间隙流场的流动状态。采用计算流体力学中的雷诺应力模型，对陀螺仪转子与定子间的封闭流场进行数值模拟，并运用粒子成像测试技术（Micro PIV）观测运动流场，测量液浮陀螺的间隙流场速度。模拟结果表明，转子上下表面与侧壁面均形成不同类型的二次流动，该现象随转速及空间尺寸的增大而增强；当转速增大到7 500 r/min时，二次流速可达到0.3 m/s，故减小空间尺寸有利于提高转子的运动稳定性。另外，文中给出了运用粒子成像测试技术(PIV)得到的流场矢量分布与流线分布图。实验证实，Micro PIV测试技术可实现对转子转速在0~1 000 r/min内的流场速度的精确观测，满足限域空间内对高速运动流场的非接触测量要求。

Abstract

The flowing state of liquid medium for the rotor at high-speed rotation in a suspended rotor gyroscope was explored. The Reynolds stress model of hydromechanics was adopted to simulate the closed flow field between the rotor and the stator

and the Micro Particle Image Velocimetry (Micro PIV) technology was used to observe the motion of flow field and to measure the speed of flowing field. The simulation results indicate that the upper and lower surfaces of the rotor both form different types of secondary flows with sidewall surfaces

and this phenomenon is enhanced with the increase of velocity and spatial dimensions. When the speed of the rotor increases to 7500 r/min

the speed of secondary flow reaches 0.3 m/s

which means that reducing space dimensions helps to improve the motion stability of the rotor. The experiment proves that Micro PIV technology is capable of accurate observation of the flow velocity with the rotor speed at 0-1 000 r/min

and can meet the requirements of non-contact test of the flow field.
