摘要
采用二次正交旋转组合方法,设计了渐开线型指尖密封结构参数和密封性能关系的实验方案,通过有限元计算获得了指尖密封结构参数对指尖密封泄漏率和磨损率的影响规律,并应用范数灰关联方法定量分析了结构参数对泄漏率和磨损率的影响程度。结果表明,指尖曲梁的宽度角对密封泄漏率的影响最大,渐开线基圆半径对密封磨损率的影响最大。
The experiment scheme of construction parameters of the involute finger seal and performances was arranged by quadratic orthogonal rotation combination design method. The effect of construction parameters of the finger seal on leakage rate and wear rate was calculated by FEM in software ANSYS and was quantitatively analyzed by grey corelation of the norm method. The result shows that the effect of finger stick width angle on leakage rate of seal is the largest and the effect of radius of involute base circle on wear rate of seal is the largest.
