摘　　要：为准确评估包装件的破损状态,改进包装设计,该文重点研究随机振动下包装件的破损机理以及振动信号的检测方法。提出一种采用线性累积损伤理论对包装件进行振动疲劳计算的新方法,并开发以MSP430F5529为系统主处理器的检测平台来检测计算中所需的相关量。最后通过实验证明此方法的可行性,为今后的包装设计提供参考。In order to accurately assess the damage state of package and improve the design of it,this paper focuses on the study of damage mechanism of packages under random vibration and testing method for vibration signal.Coming up with a new idea that conducting the fatigue calculation of random vibration by linear cumulation theory and developing a set of equipment with MSP430F5529 processor to detect the relevant quantities.At the last, proving this method is feasible through experiments and providing reference for packaging design in the future.
