Experimental and Theoretical Studies on Resonance Dynamic Effects During Silo Flow

摘要

The paper deals with the experimental and theoretical research of resonance dynamic effects during silo emptying. The influence of resonance on wall pressures in silos was investigated with model tests and FE-analyses. The model tests were carried out with a cylindrical and rectangular silo containing different bulk solis The confined flow of bulk solids between silo walls during resonance was described in model and large silos with a polar elasto-plastic constitutive law. In addition, an effective method for a full suppression of resonance effects during silo flow was proposed.
