摘　　要：阐述了高压试验机液压缸的自增强理论设计和处理试验。为了对这种由０Ｃｒ１７Ｎｉ４Ｃｕ４Ｎｂ高屈强比材料制造的超高压缸体进行自增强处理，笔者改进了传统的自增强设计理论，并提出一种新的设计计算方法。在理论设计基础上成功地用高达７２５～７３８ＭＰａ的超高压对４个缸体进行了自增强处理。This paper described the autofrettage design and test of the cylinder of High-pressure-Test machine.In order to treat this kind of ultra-high pressure cylinders with autofretiage which were made of 0Cr17Ni4Cu4Nb, the authors im-proved traditional autofrettage design theory,and pointed out a new design method.Based on the developed design,the authors successfully treated four cylinders with 725～738MPa by autofrettage.
