摘要
根据板壳理论和水弹性理论，对板壳采用有限元法、对液体采用解析法分析计算了内浮顶储液罐，即壳一液一板耦联体系的垂直自振特性。着重分析计算了２０００ｍ￣３内浮顶储液罐的固有频率。
Based on the elastic theory of plate and shell and the theory of hydro-elasticity, the characteristics of vertical self-vibration of the shell-liquid-plate system are analyzed and calculated by means of the finite element technique in which the shell and plate are modeled and analytical method inwhich liquid is treated. Fixed fraquency of 2 000 m￣3 oil storage tank with infloating roof is emphatically analyzed and calculated.
