摘要:

航空发动机压气机叶片在辊轧过程中,由于辊轧出口处构件速度大于轧辊速度,存在前滑现象,从而影响叶片辊轧成形精度。针对此问题,为实现叶片无余量辊轧成型,在分析对称辊轧前滑计算模型的基础上,提出并研究了叶片辊轧前滑,建立了叶片辊轧前滑计算模型。为验证前滑计算模型精度,设计了薄板件、V形板件和叶片这3类典型构件CAD模型,基于DEFORM-3D对其辊轧成型过程进行数值计算分析。结果表明,该模型能够精确表达截面不规则类构件辊轧前滑量,为截面变化类构件辊轧前滑研究奠定基础。

Abstract:

In the process of roll forming, the speed of component is faster than that of the roller at the end of rolling deformation zone, namely rolling forward slip phenomenon, which affects component forming precision. For the forward slip problem in the process of roll forming allowance free blade, based on the analysis of the blade roll forming process, we calculate the integral of different thicknesses along chordwise and then took the average, in this way the blade roll forward slip calculation model is established. Also, flat plat, V-shaped plate and straight grain blade are used to validate the blade roll forward slip calculation model with FEM respectively. The results show that calculation model can accurately express forward slip in rolling deformation, which lays a foundation for the forward slip study in rolling un-symmetrical component.

Key words: compressor blade, roll forming, section curve, forward slip model, FEM
