| 摘 要： | 利用ALGOR软件对锚固大型储油缸进行了动力模态分析。在分析过程中分别建立了储油和不储油的两种有限元计算模型，分别计算出了两种有限元模型的前30阶固有频率并给出了三维主震型图。从中可以明显地看出油介质对锚固大型储油罐的固有频率和主振型的影响。

| Abstract: | Dynamic modality of large sized oil tank is analysed by ALGOR software in this article.In procedure of analysing two finite element models,full of oil and empty,are established.The natural frequencies of 30 orders of two finite element models are worked out and three dimensional vibrating shape are gived separately.In two cases of full of oil and empty,the natural frequencies and vibrating shape of large sized oil tank can be found out obviously. |
