摘　　要：本文通过对４９ 个筒承式群仓试件的试验研究，得出了影响筒承式群仓自振特性的各种因素：组合筒数ｎ、高径比Ｈ／Ｄ、开洞率ξ、组合方向与开洞方向的关系及装料程度等因素。并依据试验结果，在充分考虑了各种影响因素的情况下，得出相应的基频回归公式，且该公式具有很好的计算精度。Based on experimental study of the 49 multi silos models which are supported by silos wall themselves,this paper analyzes the influencing factor of the natural vibration characteristics:silo amounts n、height diameter ratio H/D、opening extent ξ、compound direction opening direction relation and filling rate and the like.According to the experimental results,a regression equation is presented.The formula shows that there is good agreement with both experimental results and finite element results.
