摘　　要：本文通过对 35个简承式单排群仓及 14个单仓试件的试验研究 ,全面分析了组合筒数n、高宽比H D、开洞率 ξ、组合方式与开洞方向的关系及装料程序等影响自振特性的因素 ,依据试验结果 ,得出相应的基频计算回归公式 。In this paper, through the experimental study of the models of 35 cylinder?supported single row multi?silos and 14 single silos, the following influencing factors on the natural vibration characteristics are analyzed:the amount of combined silos n, height?diameter ratio H/D,ratio of opening hole ξ, relation between combined direction and opening direction, and degree of material filling. According to the experimental results, a regression formula is derived for the calculating of fundamental frequency. The formula shows a good degree of accuracy in calculation.
