摘要
采用Ｉ－ＤＥＡＳ软件将门座起重机的臂架系统作为整体模型进行了有限元动态特性分析，计算出了臂架系统的前几阶低阶固有频率，并给出了相应的振型图．
This paper presents a dynamic finite element analysis for entire portal crane boom system using I DEAS software.First few lower natural frequencies of the boom system and additional vibration mode graphes are given.It can be used as a theoretical guide for improving the quality of boom system design and correct operation of crane.
