Simulation and Analysis of the Effect of Process Parameters on Shot Peening Strengthening of TC4 Alloy

  • 摘要: 利用有限元法针对TC4钛合金的喷丸强化过程,建立了数值模型。首先,运用Abaqus建立的TC4钛合金喷丸强化的有限元模型,分别计算喷丸速度分别为40、60、80、100 m/s的模型,结果表明:当喷丸速度逐渐增大的过程中,表面残余应力,最大残余压应力和残余压应力层厚度都逐渐增大;其次,建立的TC4钛合金喷丸强化的有限元模型,分别计算了垂直入射、入射角为10°和入射角为20°的模型,结果表明:随着入射角的增大,靶材的表面粗糙度并没有显著变化,但对残余压应力的影响不可忽视,主要体现在最大残余应力由607.3 MPa逐渐减小为504.4 MPa,降幅20.4%,残余压应力层的厚度由158.5 μm降低到145.2 μm,降幅8.4%。入射角度控制在0 ~ 10°之间最合适时可以使得喷丸强化效果最优。
