| 摘 要： | 基于研制的自动化抛光系统,针对整体叶盘叶片抛光加工的颤振问题,分析了颤振后叶片表面的几何形貌。结合整体叶盘叶片自动化抛光系统,阐述了抛光颤振机理。基于颤振机理确定了编程技术优化、抛光参数优化、提高系统刚性等3种抛光颤振抑制技术,获得了优化后的刀轴方向、抛光轨迹、抛光参数及工艺填充方法。经试验验证,颤振现象,叶片波纹度、平均误差、表面粗糙度等减小,表面质量得到较大提升,颤振痕迹明显消除。

| Abstract: | Based on automated polishing machine of blisk,the geometric surface of fluttered blade was analysed.Combined with the automated polishing system of blisk blade,the flutter mechanism was described.Based on the flutter mechanism,the optimized programming technology,polishing parameters and improving system rigidity were determined to solve the flutter problem.The optimized tool axis direction,polishing track,polishing parameters and filling method were obtained.After experimental verification,the flutter is solved.And the waviness average error tends to decrease,surface quality is improved greatly.The chatter marks are eliminated obviously. |
