弹性耦合激励振动筛的摆振研究

Study on oscillation of elastically coupled and excited vibro-screen

应用逆式动力吸振原理，研究了具有分布质量的弹性耦合激励振动筛的摆振问题，导出了质量对称分布时该筛的前六阶固有频率和对谐波激励响应的解析表达式，并讨论了结构参数对振动筛频响特性和基础动荷的影响。

By use of reverse dynamic shock-absorbing principle, the authors studied the hunt problem of elastic-coupling actuation vibro-screen which has distributed mass,and derived holomorphic functions of preceding sin-step free-running frequencies and their response to harmonical actuation. Finally the authors discussed influence of design values on frequency response characteristics and basic dynamic load of a vibro-screen.
