Abstract

Vibration finishing can effectively reduce the surface roughness of blisks and change blade shape accuracy. This study investigates the influence of vibration finishing on the shape accuracy of the blade part of the blisk. The influence of the fixed attitude of the blisk on the position accuracy and profile accuracy of different measuring sections of the blade is analyzed. The changes in the blade geometry before and after vibration finishing are analyzed. The adjustment method of blade disc attitude in the machining process is developed, and the tooling used to fix the blade disc in the vibration finishing is improved. By controlling the deformation in different time periods to offset each other, the contact between the abrasive and the blade edge is reduced, effectively reducing the displacement of the blade section and the excessive wear of the edge.

振动光饰中叶片形状精度的控制方法研究
振动光饰可以有效降低叶盘的表面粗糙度,改变叶片的形状精度。本研究探讨了振动光饰对叶片部分形状精度的影响。分析了叶盘的固定姿态对叶片不同测量部分的位置精度和轮廓精度的影响。分析了振动光饰前后叶片几何形状的变化。开发了在加工过程中调整叶盘姿态的方法,并改进了在振动精加工中固定叶盘的工具。通过控制不同时间段的变形相互抵消,减少了磨料与叶片刃口的接触,有效地减少了叶片截面的位移和刃口的过度磨损。
