摘要/Abstract

摘要： 基于涡轮叶片型面结构复杂、表面均匀一致性差的现实问题,采用水平振动光整加工涡轮叶片的抛磨方法。利用离散元法(Discrete Element Method,DEM)分析了容器尺寸、加工介质填充量和振幅对涡轮叶片表面磨损深度和颗粒速度的影响,明确加工工艺参数;利用实验及测试表征,对比分析水平振动光整加工前后,涡轮叶片表面粗糙度、表面缺陷、表面形貌及表面残余应力变化情况。结果表明,当容器尺寸为80 mm×310 mm×200 mm、加工介质填充量为70 %,以及振幅为2 mm时,涡轮叶片表面加工更均匀。水平振动光整加工工艺能够有效减小涡轮叶片表面粗糙度、去除涡轮叶片表面氧化层,以及改善涡轮叶片表面残余应力。

Abstract: Based on the complex surface structure of turbine blades and the difficulty of comprehensive and uniform machining,a horizontal vibration finishing method for turbine blades was proposed. Using Discrete Element Method (DEM) the influence of container size,media filling amount,and amplitude on wear depth and particle velocity vector of blade surface was analyzed,and the process parameters were clarified. Using experiment and characterization,the changes in surface defects,surface morphology,and surface residual stress of blades before and after finishing were compared and analyzed. The results show that the blade surface is more uniform after finishing,when the container size was 80 mm×310 mm×200 mm,the media filling amount was 70 %,and the amplitude was 2 mm. The horizontal vibration finishing can effectively improve the surface roughness of blades,remove surface oxide layers of blades,and improve surface residual stress of blades.

Key words: turbine blades, horizontal vibration finishing, container size, media filling amount, amplitude
