摘　　要： 粉末冶金成形过程产品质量的实时监控是实现粉末冶金自动化生产的关键技术 .通过实验分析了粉末成形压制过程中模具模架系统振动时序模型参数与压坯密度、质量之间的关系 ,验证了采用时序模型参数识别压坯密度、质量的技术的实用性与有效性 。 Inspection and control of the quality at real_time during P/M compacting process are necessary techniques for the automatization of powder metallurgy production. The relations between the density, mass of green compact and time series model parameters based on the vibration signal of the mold system during P/M compaction are analyzed by experiments. The practicability and validity of utilizing time series model to identify the density and mass of green compact are investigated and verified. This paper presents a new approach to monitoring the quality of production at real_time during P/M compacting process.
