摘要
本文建立了拆包机工作机构的数学模型，得出了多自由度系统在周期冲击作用下的数学解，讨论了固有频率与冲击频率的关系。这将为进一步研究拆包机以及同类设备的动力特性奠定基础，为研制拆包机提供一定的参考和依据。
In this paper,the mathematical model of the working mechanism is established and the analytic solution of multi degree system under periodic impulse excitation is given.The relationship between the natural frequences and impulse excitation frequence is discussed.This model could be used as the primary fundament for designing,measuring,testing and further exploring the dynamical character of this machine and some similar units.
