摘　　要：本文运用计算机仿真软件ABAQUS模拟高压纯水射流试验,在保持靶材(7075铝合金)的靶距、喷射的移动速度、喷嘴直径不变的情况下,通过改变射流水压、射流角度来研究不同模拟状态下产生的xy曲线,包括能量曲线、塑性应变曲线、残余应力曲线、表面形貌曲线,探讨残余应力产生的规律。In this paper, the computer simulation software ABAQUS was used to simulate the high pressure pure wa- ter jet test. Under the condition of keeping the target distance （7075 aluminum alloy）, the velocity of the jet moving and the diameter of the nozzle unchanged, the angle of the jet was changed by changing the water pressure of the jet and the angle of the jet. The xy curves, including energy curve, plastic strain curve, residual stress curve and surface morphology curve, were studied to study the law of residual stress generation.
