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.
