摘要：

针对我国自主设计制造的800 MN大型模锻压机，简述了其关键参数的测试方案。在调试和试生产期间，针对压机的多种典型工况进行了测试，得到了压机垂直位移、变形、重要零件应力的数值及其与压制力的关系曲线。并在极限压力条件下对压机进行了全面测试，压机实测结果与分析计算值基本相符。并根据测试结果，对压机的关键、不可更换零件进行了寿命估算，估算出了C形板等关键件能够达到的无限寿命的要求。800 MN大型模锻压机的测试分析研究结果为压机正常生产提供了必要的技术支持。

The test plan of key parameters for 800 MN close-die forging press designed and manufactured using Chinese initiative was briefly described.The close-die forging press was tested according to several typical conditions during debugging and trial production,and the relationship between vertical direction displacement, deformation, stress on critical parts of the press and force were obtained.The press was full tested under ultimate pressure，and the test and measurement results were basically matching with the analyzed and calculated value. According to the test results，the lifetime of key and non-replaceable parts in the press was estimated，and it is proved that the C shaped plate and other key components can achieve the requirements of infinite life.So the T&M results for 800 MN close-die forging press can provide essential technical support for normal production.
