摘　　要：通过分析粉末压制成形过程中压坯密度与模架阴模板振动加速度信号之间的关系 ,提出采用ARMA谱识别压坯密度的方法 。By analyzing the relation in compacting process between the vibration acceleration signal of die plate and the density of compact,the application of utilizing ARMA spectrum to identify the density of compact has been brought forward,and give a new approach to real-time monitor the quality during powder metallurgy compacting process.

关 键 词：粉末冶金 ARMA谱 压坯密度
