摘　　要：建立马鞍型带筋整体壁板预应力喷丸成形模拟模型,通过基于数值模拟的喷丸成形参数规划流程,对壁板典型件工艺方案进行模拟分析并获得优化工艺方案。研究结果表明,采用优化后的工艺方案,典型件模拟变形量和理论变形量基本相符,最大差值位于后梁13肋处,仅为3.7mm,比初始方案减少了8.1mm。采用优化试验方案进行试验,试验变形量与模拟变形量相比,11~17肋间差值均<4mm;试验变形量与理论变形量相比,11~17肋间差值均≤2.5mm,12~16肋间差值均≤0.5mm。因此,喷丸变形模拟方法较为准确,优化方案合理可行。A simulation model for stress peen forming of saddle-shaped integrally-stiffened panels was established.Through a numerical simulation-based shot peen forming parameter planning process,the typical panel process plan was simulated and analyzed and an optimized process plan was obtained.The research results show that with the optimized process plan,the simulated deformation of the typical panel is basically consistent with the theoretical deformation.The maximum difference located at the 13th rib of the rear beam is only 3.7mm,which is 8.1mm less than the initial plan.The optimized test plan is used for the test.Compared with the simulated deformation,the differences of ribs 11–17 are less than 4mm.Compared with the theoretical deformation,the differences of ribs 11–17 are not more than 2.5mm,and the differences of ribs 12–16 are not more than 0.5mm.Therefore,the shot peening deformation simulation method is more accurate and the optimization plan is reasonable and feasible.
