摘　　要：通过对４９ 个筒承式群仓试件的试验研究，分析了组合筒数ｎ 、高径比Ｈ／ Ｄ、开洞率ζ、组合方向与开洞方向的关系及装料程度等因素对筒承式群仓自振特性的影响。研究了各种条件下平动振动。Based on experimental sutdy of the 49 multi silos models which are supported by silos wall themselves,this paper analyzes the influencing factor of the natural vibration characteristics: siol amounts n 、 height diameter ratio H/D 、opening extent ζ、compound direction opening direction relation and filling rate and the like. the effect of these influencing factors is analyzed as well. The natural vibration characteristics and regulation of translational vibration、 torsional vibration and translational and torsional vibration is also studied under all kinds of conditions.
