共振阶段带隔振台振动筛基础的动负荷

Dynamic load up ground of vibrating screen with isolator in resonance stage

计算了带隔振台大型直线振动筛对地基的动负荷,研究了二次隔振与一次隔振两种情况下对于基础的动负荷,并进行了对比,重点研究了发生共振情况下阻尼对基础动负荷的影响,本文的工作对振动筛对基础的动负荷分析具有重要意义,为进一步研究振动筛和地基基础的藕合振动奠定了基础。

The dynamic load up the ground of the large-scale linear vibrating screen with isolator was calculated;and the dynamic load up the ground at two kind of situation of the second vibration and first vibration isolation was studied and compared. The influnce on the dynamic load up the ground at the resonating situation is emphatically studied. The work has an important meaning of analyzing the dynamic load up the ground of vibrating screen, which lays the foundation for further study of the coupling vibartion by the vibrating screen and the ground foundation.
