NATURAL FREQUENCY ESTIMATION FOR A FRAME STRUCTURE USING STRUCTURAL DYNAMICS

ZHAO Zhenjun WANG Ying NING Jianguo (National Key Laboratory of Explosion and Safety Science, Beijing Institute of Technology, Beijing 100081, China)  
A method to estimate the system natural frequency using the unit natural frequency is developed by deriving the relation between the first order natural frequency of the frame structure and that of a simple frame structure. The method in this paper is verified through ANSYS, by using the finite element modal analysis. The calculation for the derrick of an oil drilling rig shows that the error is not exceeding 1%. It is shown that the method is convenient and feasible for the natural frequency estimation of frame structures in series.
