摘要
磨矿机中弹性工作介质振动型态取决于机体的运转参数，反过来又以阻尼或激励形式作用于机体。哪种形式占统治地位，取决于机体的振幅，弹性介质的形状、规格及其对运转空间的充满度。无论是阻尼还是激励，都是一个变质量过程。因而，系统不但出现高次谐波，而且还将出现亚谐波及随机振动现象。
The mede shape of the vibration of elastic actuating media of mill depends on the operating parameters of the machine body that can be dampered or excited by the system inversely,which behaviours is determined by the vibrating amplitude of the machine, the shape and size of the discrete media and their filling rate to the moving space.Whethor damping or exciting both are a curse of mass-changing. So not only super-harmonic,also subhar monic and stochastical oscillation will appear.
