摘要
通过实验得到了物料层的多项式滞回力模型,建立了双腔振动颚式破碎机的动力学模型和物料作用时的非线性振动方程,并对其非线生动力学特性进行了分析,从而得知物料、间隙和激振频率对振动系统的影响。
A polynomial hysteretic model of materials is gained by experiment. The dynamic model and the nonlinear vibratory equation considering the effect of materials are established. The non- linear dynamic performances are analyzed. And then the effects of materials, clearances and excited frequencies on the vibratory system are found.
