摘　　要：针对起重吊塔在负载停车时会出现大幅摆动、影响工作效率的现象,理论分析吊塔负载条件下所呈现的共振频率,对运动过程的加速度进行控制,避免其频谱出现共振频率。通过MATLAB仿真软件对加速度过程做快速FFT变换,控制其频谱出现在共振区域,从而避免停车过程大幅度摆动。For crane crane,there will be a large swing at the load stop moment,the phenomenon of affecting work efficiency.Theoretical analysis of resonance frequency under tower load condition,the acceleration of the motion process is controlled,avoid the resonance frequency of the spectrum.The fast FFT transform of acceleration process is carried out by MATLAB simulation software,the spectrum is controlled in the resonance region,so as to avoid the large swing of the parking process.

关 键 词：频谱分析 吊塔 大幅摆动 FFT变换
