【摘要】 本文提出了一个方程中只考虑剪切、弯曲、转动惯量效应，而塔架形状变化、平台面转动惯量及台面集中质量变化等其他影响因素均以修正系数方法确定，得出平台基本频率的简化算法。更多还原

【Abstract】 In this paper a simplified computation method of free frequency of jacket platforms is given.Shear, bending and rotary inertia effects are considered in the equation, as to jacket shape, rotary inertia and centralized mass foplatform top and so on they are all determined by using of coefficient revising method.更多还原
