摘要
桥式起重机主体结构的结构安全至关重要。在运行过程中,其结构动力学特性复杂,对主体结构进行动力学分析是实现结构安全设计的基础。该研究利用ANSYS对80t桥式起重机主体结构进行自振频率和跨中满载自振频率计算,并对其进行了瞬态动力学分析。
Structure safety of bridge crane main structure is crucial. The structural dynamics was complicate during the operation. Therefore 〉analysis of main structure dynamics is necessary for structure safety design. In order to pro-vide a basis for structural design, natural vibration frequency,including middle span natural vibration frequency, and transient dynamics of the main structure of 80 - tones bridge crane were calculated by ANSYS in this paper.
