摘要: 应用非线性数学工具对物料在强化筛中的复杂运动规律性进行了分析,推导出颗粒在强化筛中运动的递推公式.应用混沌分析方法对物料在强化筛中的运动规律进行了数值计算,并用其描述了颗粒的运动特性.结果认为,真实的料群与筛网碰撞和透筛是个十分复杂的过程,影响因素很多,用数学工具对料群碰撞、透筛过程进行精确描述目前尚有困难.

Abstract: The complex movement regularity of particle group is analysed by using no-linear mathematical tools and the recurrence formula of movement is obtained in intensifying screen. The movement patten of particle group is calculated by using chaotic analyze method and the movement property of particle group is describe. As a result, the collision of particle group and screen is a complex process that is affected by many factors. It is difficult to describle exactly by the mathematical tools at present.
