摘要

基于双线性硬化材料模型，分析了泵钢套的锻压自强化工艺。通过弹塑性分析，推导出锻压自强化钢套筒的应力、应变、残余应力、应变和冲头推力的理论计算公式。通过锻模自强化实验验证了理论公式的准确性。理论计算结果与试验结果一致，二次加载过程不影响自增强结果。理论计算公式可用于指导泵钢套的压型自强化工艺设计。

Study on swage autofrettage of steel sleeve for the high pressure plunger pump

Based on bilinear hardening material model, the swage autofrettage technology of steel sleeve for pump is analyzed. The theoretical calculation formulas of stress, strain, residual stress and strain and punch thrust of swage autofrettage steel sleeve are derived by the elastic-plastic analysis. The accuracy of the theoretical formulas is verified by the swage autofrettage experiment. The result of theoretical calculation is consistent with that of the experiment, and the process of the second loading does not affect the autofrettage result. The theoretical calculation formulas can be used to guide the swage autofrettage technology design of the steel sleeve for the pump.
