不同入射角弹丸强化残余应力场的数值模拟
|
摘要
目的通过建立有限元模型模拟研究弹丸入射角度对残余应力场和强化效果的影响。方法采用ABAQUS软件建立了单粒弹丸强化靶体的三维对称模型,对单个弹丸喷丸强化进行了数值模拟,模拟了50、75、100 m/s三种不同速度下,弹丸垂直入射作用在靶体上所产生的残余压应力场,以及30°、60°和90°三种不同入射角度下靶体上产生的残余应力场。结果不同速度下弹丸垂直入射作用在靶体上所产生的残余压应力场的模拟结果显示,随着弹丸速度的增加,靶材次表层的最大残余压应力以及压应力层深度增加。不同入射角度下靶体上产生的残余应力场深度和大小变化不相同,入射角为90°(垂直入射)时,所产生的残余压应力最大,入射角为60°时次之,入射角为30°时最小。结论模拟结果与实验结果的残余压应力最大值和曲线的变化趋势基本一致,吻合程度较高,说明所建的有限元模型可靠。在相同速度下,随着入射角度不断变大,所产生的最大残余压应力也不断增加,在垂直入射时达到最大值。
The work aims to study influence of incidence angle of shot on residual stress field and strengthening effect by establishing finite element model.Three-dimensional symmetric model of single-shot peening was established by using ABAQUS software.Numerical simulation was performed to peening of single shot.Both residual compressive stress field on target body generated by vertical incidence of shot at 50 m/s,75 m/s and 100 m/s,and that on target body at three different incidence angles of 30°,60° and 90° were simulated.The maximum residual compressive stress and depth of compressive stress layer of secondary surface of the target increased as the shot velocity increased.Depth and magnitude of the residual stress field generated at different incidence angles on the target body changed differently.The residual compressive stress was the maximum at the incidence angle was 90°(vertical incidence); higher at the incidence angle of 60°; and the minimum at the incidence angle of 30°.Variation trend of the maximum residual compressive stress and curve obtained from simulation results and experimental results are consistent,and degree of coincidence is high,indicating that the finite element model is reliable.At the identical speed,the maximum residual compressive stress increases gradually and reaches the maximum during vertical incidence as the incidence angle increases.
