摘要
本文提出一个方程中考虑剪切、弯曲、转动惯量效应,而其它如塔架形状变化,平台面转动惯量及台面集中质量变化等其它影响因素均以修正系数方法确定,给出平台基本频率的简化算法。
In this paper simplify compute method of platform basal frequency is given, in consideration of effects of shear,bend and rotary inertia in equation. Anather effects, such as shape change of jacket, rotary inertia and concentrate mass change of platform, are determined by use of revise coefficent.
